[Machine] From the Prophet ﷺ, he said: Gabriel and Michael came to me, and Gabriel said: Recite the Qur'an on one letter. Then Michael said: Increase it. He said: Recite it on seven letters, all of which are comprehensive and sufficient as long as a verse of mercy is not sealed with punishment or a verse of punishment is not sealed with mercy.  

أحمد:٢٠٤٢٥ – حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ حَمَّادِ بْنِ سَلَمَةَ عَنْ عَلِيِّ بْنِ زَيْدٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكَرَةَ عَنْ أَبِيهِ

عَنِ النَّبِيِّ ﷺ قَالَ أَتَانِي جِبْرِيلُ وَمِيكَائِيلُ فَقَالَ جِبْرِيلُ اقْرَأِ الْقُرْآنَ عَلَى حَرْفٍ وَاحِدٍ فَقَالَ مِيكَائِيلُ اسْتَزِدْهُ قَالَ اقْرَأْهُ عَلَى سَبْعَةِ أَحْرُفٍ كُلِّهَا شَافٍ كَافٍ مَا لَمْ تُخْتَمْ آيَةُ رَحْمَةٍ بِعَذَابٍ أَوْ آيَةُ عَذَابٍبِرَحْمَةٍ

[Machine] "O Muhammad, recite the Quran accurately." Mikha'il (the angel) said, "Increase it." So he increased it. He said, "Recite it with two letters." Mikha'il said, "Increase it." So he increased it until it reached seven letters. He said, "All (the verses) are either an admonition of punishment combined with mercy or a verse of mercy combined with punishment, like your saying: 'Come and approach and so on and leave and hasten and be quick.'"
