The Messenger of Allah ﷺ said: “Whoever says at the end of every Fajr prayer, while his feet are still folded, before speaking: ‘None has the right to be worshipped but Allah, Alone without partner, to Him belongs all that exists, and to Him is the praise, He gives life and causes death, and He is powerful over all things, (Lā ilāha illallāh, waḥdahu lā sharīka lahu, lahul-mulku wa lahul-ḥamdu, yuḥyī wa yumītu, wa huwa ʿalā kulli shay’in qadīr)’ ten times, then ten good deeds shall be written for him, ten evil deeds shall be wiped away from him, ten degrees shall be raised up for him, and he shall be in security all that day from every disliked thing, and he shall be in protection from Shaitan, and no sin will meet him or destroy him that day, except for associating partners with Allah.” (Using translation from Tirmidhī 3474)
قَالَ رَسُولُ اللهِ ﷺ مَنْ قَالَ دُبُرَ صَلَاةِ الْفَجْرِ وَهُوَ ثَانِي رِجْلِهِ قَبْلَ أَنْ يَتَكَلَّمَ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ يُحْيِي وَيُمِيتُ بِيَدِهِ الْخَيْرُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ عَشْرَ مَرَّاتٍ كَتَبَ اللهُ لَهُ بِكُلِّ وَاحِدَةٍ قَالَهَا مِنْهُنَّ حَسَنَةً وَمَحَى عَنْهُ سَيِّئَةً وَرُفِعَ بِهَا دَرَجَةً وَكَانَ لَهُ بِكُلِّ وَاحِدَةٍ قَالَهَا عَتَقُ رَقَبَةٍ وَكَانَ يَوْمَهُ ذَلِكَ فِي حِرْزٍ مِنْ كُلِّ مَكْرُوهٍ وَحُرِسَ مِنَ الشَّيْطَانِ وَلَمْ يَنْبَغِ لِذَنْبٍ أَنْ يُدْرِكَهُ فِي ذَلِكَ الْيَوْمِ إِلَّا الشِّرْكُ بِاللهِ
