Holy prophet marriages
We believe that all prophets and Imams (descendents of holy prophet) are infallible in all stage of immunity which is: immaculacy of ignorance, committing sin, doing wrongs by mistake or erroneously. In addition, prophets receive revolution perfectly and preach it as well. Infallibles enjoy types of immunity even in their childhood. Complete faith in God and exclusive knowledge always pave the way of infallibility and being everlasting pattern. But the question is about various women of holy prophet. Is it damages his infallibility and being perfect symbol for ever? It is mentioned in Quran: certainly you have in the messenger Allah an excellent exemplar for him who hopes in Allah and the latter day and remembers Allah much. ( al-ahzab 121)
With cursory glance to the history the answer is clear.
It has been written by impartial truth-seeking historians, both Muslims and Christians, that the numerous marriages of the Holy Prophet of Islam, were by no means due to sensuality and sexual passions, for if this were so, he would never have married Khadija who was 40 years old and who had lost most of her beauty and vivacity in the houses of her two former husbands, when he himself was only 25, the age of the sexual passions of youth and when young men are preoccupied with choosing young wives.
The Prophet lived most sincerely and faithfully for 25 years with Khadija, and, though many beautiful Arab maidens and women were eagerly longing to marry him, not once did he take another wife during his married life with Khadija. No doubt if our Holy Prophet were interested in following sexual passions, he could not have refrained from mating with young women during this long period. The conditions and circumstances that necessitated the several marriages of the Prophet should be studied. The main reasons for his marriages are the following:
1. To take care of the orphans and the destitute
The Prophet took some of his wives in order to maintain the prestige and reputation they had when they previously had been living in comfort and honour but whose faith and honour were endangered due to the loss of their guardians - husbands, fathers, sons and their tribes - forcing them to abandon Islam and select polytheism and atheism. Sauda was like this. Her husband passed away in Ethiopia, where they had migrated, leaving her alone and without support. The Prophet, who had lost Khadija and had no other wife, married Sauda.
Zaynab the daughter of Khuzayma was a widow who had, after her husband's death, fallen into poverty. She had always been a generous and benevolent woman, known as `the mother of the poor'. To guard her honour and reputation, the Prophet took Zaynab as his wife. She passed away in the lifetime of God's Messengers. Umm Salma, too, was faithful and aged and had helpless orphans. She was another wife of our Prophet.
2. To establish proper laws and customs
Another reason was to establish proper laws and customs and to nullify wrong customs and beliefs of the period of ignorance and idol-worship. At the Holy Prophet's order, Zaynab, the daughter of Jahash and the Prophet's cousin, married Zayd ibn Harith. This was an example of annuling class differences which Islam forbids. Zaynab was a granddaugher of the Quraysh chieftain Abdul Muttalib and Zayd's family were slaves. The Holy Prophet had bought his freedom. For these reasons, Zaynab considered herself superior to her husband, Zayd, thus making her marital life bitter and unbearable. No matter how much the Holy Prophet advised them, she did not change her manners, so finally Zayd, feeling no love for her any longer, divorced her.
At God's command, the great Prophet of Islam married Zaynab after her husband, Zayd, had divorced her in order to wipe out the custom of not marrying the former wives of adopted sons (for they regarded their adopted sons as their real sons), which custom was unduly prevalent among the people in the dark periods of paganism.
