﴿ وَلْيَسْتَعْفِفِ ٱلَّذِينَ لَا يَجِدُونَ نِكَاحًا حَتَّىٰ يُغْنِيَهُمُ ٱللَّهُ مِن فَضْلِهِۦ ۗ وَٱلَّذِينَ يَبْتَغُونَ ٱلْكِتَٰبَ مِمَّا مَلَكَتْ أَيْمَٰنُكُمْ فَكَاتِبُوهُمْ إِنْ عَلِمْتُمْ فِيهِمْ خَيْرًۭا ۖ وَءَاتُوهُم مِّن مَّالِ ٱللَّهِ ٱلَّذِىٓ ءَاتَىٰكُمْ ۚ وَلَا تُكْرِهُوا۟ فَتَيَٰتِكُمْ عَلَى ٱلْبِغَآءِ إِنْ أَرَدْنَ تَحَصُّنًۭا لِّتَبْتَغُوا۟ عَرَضَ ٱلْحَيَوٰةِ ٱلدُّنْيَا ۚ وَمَن يُكْرِههُّنَّ فَإِنَّ ٱللَّهَ مِنۢ بَعْدِ إِكْرَٰهِهِنَّ غَفُورٌۭ رَّحِيمٌۭ ﴾

“And as for those who are unable to marry, let them live in continence until God grants them sufficiency out of His bounty, And if any of those whom you rightfully possess desire [to obtain] a deed of freedom, write it out for them if you are aware of any good in them: and give them [their share of the wealth of God which He has given you. And do not, in order to gain some of the fleeting pleasures of this worldly life, coerce your [slave] maidens into whoredom if they happen to be desirous of marriage; and if anyone should coerce them, then, verily, after they have been compelled [to submit in their helplessness], God will be much-forgiving, a dispenser of grace!”

Islam clearly approves of married life for both men and women. In case certain persons remain unmarried, due to lack of resources, it is necessary that all the members of society unanimously view it as a common problem and do not rest content until it is solved. In the period when Islam came into existence, the system of owning slaves was prevalent in Arabia and, indeed, throughout the whole world. Islam, following its basic principles, started abolishing slavery in a very systematic though gradual manner. One of the methods followed was known as makatibah. The literal meaning of kitab or makatibah is ‘writing’. Here this term denotes a bond by which a male or female slave promises his or her owner to earn for him a specified amount within stipulated time, after which he or she will be free. Both male and female slaves were thus being set free either by makatibah or by other methods, so much so, that by the end of the period of early Islamic history (the period of the ‘four rightly guided caliphs’) the institution of slavery had been almost completely abolished. In pre-Islamic times and even in the very early period of Islam, there were people who used to make their slave girls work as prostitutes. Abdullah ibn Ubayy had many slave girls whom he forced into prostitution and thus earned a profit out of them. When one of these slave girls embraced Islam and wanted to give up prostitution, Abdullah ibn Ubayy started harassing her. Ultimately, at the behest of the Prophet Muhammad, she was freed from his clutches by paying for her freedom.
