I said to the Prophet ﷺ, "Hisham bin Mughira used to maintain ties of kinship, host guests, ransom captives, and feed the hungry. Had he lived to see Islam, would any of that have benefited him?"He replied, "No. He gave only for the sake of this world, for its renown and its praise, and he never once said, 'My Lord, forgive me on the Day of Judgment.'"
قلت للنبي ﷺ: إن هشام بن المغيرة كان يصل الرحم، ويقري الضيف، ويفل العناة، ويطعم الطعام، ولو أدرك أسلم، هل ذلك نافعه؟ قال: لا، إنه كان يعطي للدنيا وذكرها و حمدها، ولم يقل يوما قط: رب اغفر لي يوم الدين.
Reported by Abu Yaala (6965) - and this is his wording - and Ibn Abu Shayba in his Musnad - as found in Matalib Aliyah - (2871), and Tabarani in Al-Kabir (23/606), all of them through various routes from Mansur, from Mujahid, from Umm Salama, who narrated it as mentioned. Its chain of transmission is sahih.Haythami said in Majma (1/118), "Reported by Tabarani in Al-Kabir and by Abu Yaala, and its narrators are the narrators of the Sahih."Her statement, "Hisham bin Mughira," refers to the uncle of Umm Salama.
