Ibn Mas'ud reported God’s messenger as saying, “If anyone gives liberally to his family on the day of ‘Ashura, God will be liberal to him the rest of the year.” Sufyan said he had tested it and found it to be so. Razin transmitted it, and Baihaqi in Shu’ab al-iman transmitted it from , Abu Huraira, Abu Sa'id andjabir, but declared it to be weak.

وَعَنِ ابْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ وَسَّعَ عَلَى عِيَالِهِ فِي النَّفَقَةِ يَوْمَ عَاشُورَاءَ وَسَّعَ اللَّهُ عَلَيْهِ سَائِرَ سَنَتِهِ» . قَالَ سُفْيَانُ: إِنَّا قَدْ جربناه فوجدناه كَذَلِك. رَوَاهُ رزين وَرَوَى الْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ عَنْهُ وَعَنْ أبي هُرَيْرَة وَأبي سعيد وَجَابِر وَضَعفه
