Al-As ibn Wa'il () was the father of the Sahabi(Companion) ['Amr ibn al-'As]] and Hisham ibn al-A'as.
He robed a yemeni of his good in a trade. The Hilf al-Fudul was set in place at this occasion, in order to bring back justice to the yemeni merchant and those without protection in meccan society.
He was rumored to have had a relationship with Layla bint Harmalah.
Surat al-Kawthar is the 108th surah of the Qur'an, and the shortest. According to Ibn Ishaq, it was revealed in Makka, some time before the Isra and Miraj, when A'as ibn Wa'il as-Sahmi said of Muhammad that he was "a man who is cut off (from having a male progenitor) is of no consequence, and if he were killed, he would be forgotten."
He never became a Muslim and left a will to his two sons.
