عَنْ أُمِّ حَبِيبَةَ قَالَتْ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ حَافَظَ عَلَى أَرْبَعِ رَكَعَاتٍ قَبْلَ الظُّهْرِ وَأَرْبَعٍ بَعْدَهَا حَرَّمَهُ اللَّهُ عَلَى النَّارِ» . رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ وَابْنُ مَاجَه
Translation
‘Abdallah b. as-Sa’ib said God’s Messenger used to pray four rak'as before the noon prayer, after the sun had passed the meridian, saying, “It is an hour at which the gates of heaven are opened, and I like a good deed of mine to ascend at that time.” Tirmidhi transmitted it.
