2. The Prophet came to establish morality and assure every Muslim of security, protection, moral integrity and a decent life. His mission was put to the test in his life and did not stay in the stationary form of theory. As usual, he took the hardest part and did his share in the most inconvenient manner. Wars and persecutions burdened the Muslims with many widows, orphans and divorcees. They had to be protected and maintained by the surviving Muslim men. It was his practice to help these women get resettled by marriage to his companions. Some women were rejected by the companions and some others sought his personal patronage and protection. Realizing fully their conditions and sacrifices for the cause of Islam, he had to do something to relieve them. One course of relief was to take them as his own wives and accept the challenge of heavy liabilities. So he did and maintained more than one wife at a time which was no fun or easy course. He had to take part in the rehabilitation of these widows, orphans and divorcees because he could not ask his companions to do things which he himself was not prepared to do or participate in. these women were trusts of the Muslims and had to or participate in. These women were trusts of the Muslims and had to kept jointly. What he did, then, was his share of responsibility, and as always his share was the largest and heaviest. That is why he had more than one wife, and had more wives than any of his companions.
3. There were many war prisoners captured by the Muslims and entitled to security and protection. They were not killed or denied any right, human or physical. On the contrary, they were helped to settle down through legal marriages to Muslims instead of being taken as concubines and common mistresses. That also was another moral burden on the Muslims and had to be shouldered jointly as a common responsibility.
Here, again, Muhammad carried his share and took some responsibilities by marrying two of those captives.
4. The Prophet contracted some of his marriages for sociopolitical reasons. His principal concern was the future of Islam. He was most interested in strengthening the Muslims by all bonds. That is why he married the minor daughter of Abu Bakr, his First Successor, and the daughter of Umar, his Second Successor. It was by his marriage to Juwairiah that he gained the support for Islam of the whole clan of Bani al-Mustaliq and their allied tribes. It was through marriage to Safiyah that he neutralized a great section of the hostile Jews of Arabia. By accepting Mary the Copt from Egypt as his wife, he formed a political alliance with a king of great magnitude.
It was also a gesture of friendship with a neighboring king that Muhammad married Zaynab who was presented to him by the Negus of Abyssinia in whose territory the early Muslims found safe refuge.
