Whoever says, ten times: There is no god but Allah alone, Who has no partner, to Him belongs the sovereignty, to Him belongs the praise, and He is Omnipotent over all things; will be as though he emancipated four slaves from the offspring of Isma‘īl. [Al-Bukhari]
«مَنْ قَالَ: لَا إلَهَ إلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ، وَلَهُ الْحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ عَشْرَ مَرَّاتٍ كَانَ كَمَنْ أَعْتَقَ أَرْبَعَةَ أَنْفُسٍ مِنْ وَلَدِ إسْمَاعِيلَ». [متفق عليه]
