Hadith 489

Sahih Bukhari

Book 65: Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))

Chapter 1

What has been said about Fãtihat al-Kitab (i.e., the Opening of the Book)

باب مَا جَاءَ فِي فَاتِحَةِ الْكِتَابِ

It is also called Umm-ul-Kitab (i.e., the Mother of the Book), because it is the first Surah that has been written in the copies of the Quran, and it is also the first Surah to be recited in Salat (prayer).
وَسُمِّيَتْ أُمَّ الْكِتَابِ أَنَّهُ يُبْدَأُ بِكِتَابَتِهَا فِي الْمَصَاحِفِ، وَيُبْدَأُ بِقِرَاءَتِهَا فِي الصَّلاَةِ. وَالدِّينُ الْجَزَاءُ فِي الْخَيْرِ وَالشَّرِّ، كَمَا تَدِينُ تُدَانُ. وَقَالَ مُجَاهِدٌ: بِالدِّينِ بِالْحِسَابِ. {مَدِينِينَ} مُحَاسَبِينَ.
Sahih al-Bukhari 4967
حَدَّثَنَا الْحَسَنُ بْنُ الرَّبِيعِ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنِ الأَعْمَشِ، عَنْ أَبِي الضُّحَى، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا صَلَّى النَّبِيُّ صلى الله عليه وسلم صَلاَةً بَعْدَ أَنْ نَزَلَتْ عَلَيْهِ ‏{‏إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ‏}‏ إِلاَّ يَقُولُ فِيهَا ‏"‏ سُبْحَانَكَ رَبَّنَا وَبِحَمْدِكَ، اللَّهُمَّ اغْفِرْ لِي ‏"‏‏.‏
Aisha:

"When the "Surat-An-Nasr", 'When comes the Help of Allah and the conquest,' had been revealed to the Prophet (ﷺ) he did not offer any prayer except that he said therein, "Subhanka Rabbana wa bihamdika; Allahumma ighfirli (I testify the Uniqueness of our Lord, and all the praises are for Him: O Allah, forgive me!")
