The Command to marry

These clear Ayat include a group of unambiguous rulings and firm commands.
(And marry those among you who are single (Al-Ayama)....) This is a command to marry. The Prophet said:
(O young men, whoever among you can afford to get married, let him marry, for it is more effective in lowering the gaze and protecting the private parts. Whoever cannot do that, then let him fast, for it is a protection for him.) This was recorded in the Two Sahihs from the Hadith of Ibn Mas`ud. In the Sunan, it was recorded from more than one person that the Messenger of Allah said:
(Marry and have children, for I will be proud of you before the nations on the Day of Resurrection.) The word Al-Ayama, the plural form of Ayyim, is used to describe a woman who has no husband and a man who has no wife, regardless of whether they have been married and then separated, or have never been married at all. Al-Jawhari reported this from the scholars of the (Arabic) language, and the word is applied to men and women alike.
(If they be poor, Allah will enrich them out of His bounty.) `Ali bin Abi Talhah reported from Ibn `Abbas: "Allah encouraged them to get married, commanded both free men and servants to get married, and He promised to enrich them.''
(If they be poor, Allah will enrich them out of His bounty.) It was recorded that Ibn Mas`ud said: "Seek the richness through marriage, for Allah says:
(If they be poor, Allah will enrich them out of His bounty.)'' This was recorded by Ibn Jarir. Al-Baghawi also recorded something similar from `Umar. It was reported from Al-Layth from Muhammad bin `Ajlan from Sa`id Al-Maqburi from Abu Hurayrah that the Messenger of Allah said:
(There are three whom it is a right upon Allah to help: one who gets married seeking chastity; a slave who makes a contract with his master with the aim of buying his freedom; and one who fights for the sake of Allah.) This was recorded by Imam Ahmad, At-Tirmidhi, An-Nasa'i and Ibn Majah. The Prophet performed the marriage of a man who owned nothing but his waist wrap, and could not even buy a ring made of iron, but he still married him to that woman, making the Mahr his promise to teach her whatever he knew of the Qur'an. And it is known from the generosity and kindness of Allah that He provided him with whatever was sufficient for her and for him.
