What did Suhail bin 'Amr stipulate as part of the terms of the truce between him and the Prophet Muhammad (saw) following the 'Umra of Al-Hudaibiya?
 Narrated `Urwa bin Az-Zubair:                     That he heard Marwan bin Al-Hakam and Al-Miswar bin Makhrama relating one of the events that happened to Allah's Apostle in the `Umra of Al-Hudaibiya. They said, "When Allah's Apostle concluded the truce with Suhail bin `Amr on the day of Al-Hudaibiya, one of the conditions which Suhail bin `Amr stipulated, was his saying (to the Prophet), "If anyone from us (i.e. infidels) ever comes to you, though he has embraced your religion, you should return him to us, and should not interfere between us and him."

Her relatives came, asking Allah's Apostle to return her to them, and in this connection, Allah revealed the Verses dealing with the believing (women). Aisha said, "Allah's Apostle used to test all the believing women who migrated to him, with the following Verse:-- "O Prophet! When the believing Women come to you, to give the pledge of allegiance to you." (60.12) `Urwa's uncle said, "We were informed when Allah ordered His Apostle to return to the pagans what they had given to their wives who lately migrated (to Medina) and we were informed that Abu Basir..." relating the whole narration.
