وَعَنْ أَبِي أَيُّوبَ رضى الله عنه
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«مَنْ قَالَ: لَا إِلَهَ إِلَّا اَللَّهُ، وَحْدَهُ لَا شَرِيكَ لَهُ عَشْرَ مَرَّاتٍ، كَانَ كَمَنْ أَعْتَقَ أَرْبَعَةَ أَنْفُسٍ مِنْ وَلَدِ إِسْمَاعِيلَ»
“Whoever says ten times: ‘None has the right to be worshipped except Allah alone, without partner, to Him belongs all sovereignty and praise. He gives life and causes death. He is over all things, Omnipotent will have a reward equivalent to that of emancipating four of the descendants of lsmail from slavery.’ Agreed upon.”
