وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ صَامَ يَوْمًا ابْتِغَاءَ وَجْهِ اللَّهِ بَعَّدَهُ اللَّهُ مِنْ جَهَنَّمَ كَبُعْدِ غُرَابٍ طَائِرٍ وَهُوَ فرخ حَتَّى مَاتَ هرما» . رَوَاهُ أَحْمد وَرَوَى الْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ عَنْ سَلَمَةَ بن قيس

He reported God’s messenger as saying, “If anyone out of a desire to please God fasts for a day, God will remove him from jahannam as far as a crow flies from the time it is a young bird till it dies of old age.” Ahmad transmitted it, and Baihaqi transmitted it in Shu'ab al-iman from Salama b. Qais.
