Compiled by Imam Abu Isa at-Tirmidhi
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ، أَخْبَرَنَا صَاعِدٌ الْحَرَّانِيُّ، حَدَّثَنَا زُهَيْرٌ، أَخْبَرَنَا قَابُوسُ بْنُ أَبِي ظَبْيَانَ، أَنَّ أَبَاهُ، حَدَّثَهُ قَالَ قُلْنَا لاِبْنِ عَبَّاسٍ أَرَأَيْتَ قَوْلَ اللَّهِ عَزَّ وَجَلَّ : (ما جَعَلَ اللَّهُ لِرَجُلٍ مِنْ قَلْبَيْنِ فِي جَوْفِهِ ) مَا عَنَى بِذَلِكَ قَالَ قَامَ نَبِيُّ اللَّهِ صلى الله عليه وسلم يَوْمًا يُصَلِّي فَخَطَرَ خَطْرَةً فَقَالَ الْمُنَافِقُونَ الَّذِينَ يُصَلُّونَ مَعَهُ أَلاَ تَرَى أَنَّ لَهُ قَلْبَيْنِ قَلْبًا مَعَكُمْ وَقَلْبًا مَعَهُمْ . فَأَنْزَلَ اللَّهُ : (ما جَعَلَ اللَّهُ لِرَجُلٍ مِنْ قَلْبَيْنِ فِي جَوْفِهِ ) . حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنِي أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، نَحْوَهُ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ .
"Qabus bin Abi Zabyan narrated to us, that his father narrated to him, he said: 'We said to Ibn 'Abbas: "What is the meaning of the saying of Allah the Mighty and Sublime: Allah has not made for any man two hears inside his body.? (33:4)" He said: "The Prophet of Allah (ﷺ) stood one day for Salat, then he was unsure (regarding how much he had prayed). The hypocrites who prayed with him said: 'Don't you see that he has two hearts, a heart with you and another with them?' So Allah revealed: 'Allah has not made for any man two hearts inside his body.'"
