Hadith
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا بِشْرُ بْنُ السَّرِيِّ، حَدَّثَنَا نَافِعُ بْنُ عُمَرَ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، قَالَ قَالَتْ أَسْمَاءُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَنَا عَلَى، حَوْضِي أَنْتَظِرُ مَنْ يَرِدُ عَلَىَّ، فَيُؤْخَذُ بِنَاسٍ مِنْ دُونِي فَأَقُولُ أُمَّتِي. فَيَقُولُ لاَ تَدْرِي، مَشَوْا عَلَى الْقَهْقَرَى ". قَالَ ابْنُ أَبِي مُلَيْكَةَ اللَّهُمَّ إِنَّا نَعُوذُ بِكَ أَنْ نَرْجِعَ عَلَى أَعْقَابِنَا أَوْ نُفْتَنَ.
Narrated Asma':The Prophet (ﷺ) said, "I will be at my Lake-Fount (Kauthar) waiting for whoever will come to me. Then some people will be taken away from me whereupon I will say, 'My followers!' It will be said, 'You do not know they turned Apostates as renegades (deserted their religion).'" (Ibn Abi Mulaika said, "Allah, we seek refuge with You from turning on our heels from the (Islamic) religion and from being put to trial
