Jami` at-Tirmidhi, Volume 6, Book 45, Hadith 3553 (DarusSalam) ⓘ
Abu Ayyub Al-Ansari narrated that the Messenger of Allah said: “Whoever says ten times: ‘None has the right to be worshipped by Allah, Alone, without partner, to Him belongs all that exists, and to Him belongs the praise, [He gives life and causes death,] and He has power over all things, (Lā ilāha illallāh, waḥdahu lā sharīka lahu, lahul-mulku wa lahul-ḥamdu, [yuḥyī wa yumītu,] wa huwa `alā kulli shai’in qadīr)’ it is for him equal to freeing four slaves among the offspring of Isma`il.”
حَدَّثَنَا مُوسَى بْنُ عَبْدِ الرَّحْمَنِ الْكِنْدِيُّ الْكُوفِيُّ، حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ، قَالَ وَأَخْبَرَنِي سُفْيَانُ الثَّوْرِيُّ، عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنِ الشَّعْبِيِّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنْ أَبِي أَيُّوبَ الأَنْصَارِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ قَالَ عَشْرَ مَرَّاتٍ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ يُحْيِي وَيُمِيتُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ . كَانَتْ لَهُ عِدْلَ أَرْبَعِ رِقَابٍ مِنْ وَلَدِ إِسْمَاعِيلَ " . قَالَ وَقَدْ رُوِيَ هَذَا الْحَدِيثُ عَنْ أَبِي أَيُّوبَ مَوْقُوفًا .
