Umm Salamah reported: She said, “O Messenger of Allah, Hisham ibn al-Mughirah used to feed the hungry, entertain the guest, uphold family ties, and free captives. Were Islam to have reached him, he would have embraced it. Will he be rewarded for any of it?” The Prophet, peace and blessings be upon him, said, “Verily, your uncle used to give charity for the sake of the world and to be remembered fondly therein. He did not say for even a single day: Forgive me on the Day of Judgment.”

عَنْ أُمِّ سَلَمَةَ قَالَتْ يَا رَسُولَ اللهِ إِنَّ هِشَامَ بْنَ الْمُغِيرَةِ كَانَ يُطْعِمُ الطَّعَامَ وَيَقْرِي الضَّيْفَ وَيَصِلُ الرَّحِمَ وَيَفُكُّ الْعَانِيَ فَلَوْ أَدْرَكَكَ أَسْلَمَ فَهَلْ لَهُ فِي ذَلِكَ أَجْرٌ قَالَ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِنَّهُ عَمُّكِ كَانَ يُعْطِي لِلدُّنْيَا وَذِكْرِهَا وَجَمَالِهَا وَمَا قَالَ يَوْمًا قَطُّ اغْفِرْ لِي يَوْمَ الدِّينِ
