Hadith 204

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 4682
حَدَّثَنِي إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنِ ابْنِ جُرَيْجٍ، وَأَخْبَرَنِي مُحَمَّدُ بْنُ عَبَّادِ بْنِ جَعْفَرٍ، أَنَّ ابْنَ عَبَّاسٍ، قَرَأَ ‏{‏أَلاَ إِنَّهُمْ تَثْنَوْنِي صُدُورُهُمْ‏}‏ قُلْتُ يَا أَبَا الْعَبَّاسِ مَا تَثْنَوْنِي صُدُورُهُمْ قَالَ كَانَ الرَّجُلُ يُجَامِعُ امْرَأَتَهُ فَيَسْتَحِي أَوْ يَتَخَلَّى فَيَسْتَحِي فَنَزَلَتْ ‏{‏أَلاَ إِنَّهُمْ يَثْنُونَ صُدُورَهُمْ‏}‏
Muhammad bin `Abbas bin Ja`far:

Ibn `Abbas recited. "No doubt! They fold up their breasts." I said, "O Abu `Abbas! What is meant by "They fold up their breasts?" He said, "A man used to feel shy on having sexual relation with his wife or on answering the call of nature (in an open space) so this Verse was revealed:-- "No doubt! They fold up their breasts."
