For the encouragement, inducement and interest of marriage among mumineen, Allah Ta'ala mentions in the Qur'an:
“And of His signs is that He has created of yourselves, spouses for you that you might rest in them and He has set love and mercy between you. Surely in that are signs for a people who consider.”
“And Allah Ta'ala is He Who has created man from water, and has appointed for him kindred by blood (has appointed ancestors for him) and kindred by marriage (has appointed in laws for him); for Allah is the most Powerful.”
“Marry the spouseless among you, and your slaves and handmaidens who are virtuous; if they are poor, Allah will enrich them with His bounty; Allah is All-embracing, All-knowing. And let those who find not the means to marry be abstinent till Allah enriches them with His bounty.”
Imaam Ja'far us-Saadiq (AS), his fathers and his ancestors said: Rasulullah (SAWS) said that, ‘He who desires to meet Allah Ta'ala in a state of piousness and purity should marry and make his spouse and lead a virtuous life with his wife.'
Rasulullah (SAWS) further said: ‘He who wishes to follow my character, should abide to my practices (sunnat), and marriage is one of my sunnat. He also said that, ‘When a man marries in his manhood, the shaitaan (satan), cries out repeatedly and yells that, “This man has protected two-thirds of his religion from me”, and let him fear Allah in his remaining third of life by doing good deeds.'
Maulana Ali (AS) said: Whenever any of the associates of Rasulullah (SAWS) married, he used to say, “Kamola deenohu” meaning his faith ( imaan ) has been perfected, completed.
Maulana Ali (AS) has narrated an incident and said: Once Usmaan bin Maz'oon came to Rasulullah (SAWS) and said, ‘O Rasulullah (SAWS), I am beset by the pleasurable thoughts, but I will not take any action without seeking direction from you first.' Rasulullah (SAWS) said, ‘And what is it that your soul urges you, O Usmaan?' He said, ‘I am thinking of severing marital relations with my wife Khawla.' Rasulullah (SAWS) said, ‘Do not do so, O Usmaan.' Verily, when a faithful one takes his wife by his hands, Allah records ten good deeds to his credit and erases ten misdeeds; and if he kisses her, Allah gives him credit for one hundred good deeds and erases his one hundred misdeeds; and when he performs intercourse with her, Allah gives him credit of one thousand good deeds and erases a thousand misdeeds and angels visits the couple. And when that couple takes the ritual bath (ghusl) of Janaabat , for every drop of water that fall from their hairs, Allah records one good deed for them and erases their one misdeed. If the couple takes the ghusl in a cold night, Allah tells His angels, ‘Observe this couple, they are taking ghusl in a cold night, having knowledge that I am their Lord. I bear witness that I have pardoned their sins', and if conception occurs that night, then their child will become tranquility for their mind and coolness of their eyes and will be obedient to them in the Paradise .' Then Rasulullah (SAWS) placed his hand on the chest of Usmaan and said, ‘O Usmaan, do not turn away from my sunnat; verily he who will turn his face away from my sunnat will be met by angels on the Day of Qayaamat who will turn his face away from my Pond (Hauz-e-Kausar and Aab-e-Salsabeel).
Rasulullah (SAWS) has said: “When a faithful man approaches his faithful wife for the intercourse, two angels will enclose him, and then he is like one who draws his sword for the cause of Allah. And when he is free from her after the intercourse, his sins are shed, just as the leaves fall from a tree in autumn; and when he performs ghusl, he is altogether separated from all sins.” He also said that, ‘As the faith of man in Allah increases, love for his wife increases equally.' He said that Allah has conferred three unique favors to His prophets, which are their practices (sunnat) and to act accordingly is meritorious, 1: ‘Itr (attar; to apply attar), 2: Sewaak (tooth-stick; to do miswaak, cleaning the teeth), 3: Zewaaj (wife; to marry).
Rasulullah (SAWS) has said: “Lead your brides to their new home (home of their bridegrooms) at night for zefaaf (the first night after marriage), and give a feast (lunch) on the day of marriage.” He also said that you should not remain awake at night except for three purposes: Reading the Qur'an or offering the namaaz; seeking knowledge; and leading the bride to her new home for zefaaf. He said, ‘Let a man prepare himself to go to his wife as he desires her to prepare herself for him.' This he referred to the cleanliness of both the partners.
Rasulullah (SAWS) said: “When a wife is brought to her husband after the marriage, let him pray two rak'ats of prayer and place his hand on her forehead and recite the following verses:
“O Allah, Make my wife auspicious for me, and make me auspicious for her. As you have united us, unite us in kindness, success, and blessing, and when you separate us, separate us in fairness.”
After reciting the above verses, he should say the following;
“O Allah, all praise to Allah Who has guided me rightly when I was on the wrong path; Who has brought to riches from poverty; has given me fame from my common position; has given honour to me in my dishonored condition; given protection to my family; coupled my celibacy with marital life; given servant for my service; has made my loneliness entertaining; and removed my wickedness (removed my nine difficulties and given me nine comforts). O Allah, I thank you liberally, kindly invoking Your blessing for what You have given me and for what You have deemed to be my portion to honour me.”
Imaam Ja'far us-Saadiq (AS) said, “When a man wishes to have sexual intercourse with his wife, let him take the name of Allah, and pray to Him to the best of his ability”. He also directed that, “When she comes to you, tell her relatives that she should be ritually pure, and you too should be in the same condition. Then do not do intercourse until you have prayed two rak'ats, and instruct her to do the same. Then praise Allah, send blessings to Rasulullah (SAWS), and supplicate, and at the end ask her to say ‘ameen'. The bridegroom should say:
“O Allah. If you have decreed a successor to follow me, then let him be sincere to You in Imaan and do not give shaitaan any share, or interest, or portion; more or less in him; and make my child clean and pure (pious); and do not create in him any deficiency or superfluity and make his end happy.”

May every mumineen have their hearts inculcated with Walaayat and Ulfat of Saheb-e-Da'wat without which one cannot attain the ultimate and permanent abode in the Hereafter.
