"We heard Abu Umamah Al-Bahili say: 'I heard 'Amrah bin 'Abasah say: I said: 'O Messenger of Allah, is there any moment which brings one close to Allah than another, or any moment that should be sought out for remembering Allah? He said: 'Yes, the closest that the Lord is to His slave is in the last part of the night, so if you can be among those who remember Allah at that time, then do so. For prayer is attended and witnessed (by the angels) until the sun rises, then it rises between the two horns of the Shaitan, that is the time when the disbelievers pray, so do not pray until the sun had risen to the height of a spear and its rays have disappeared. Then prayer is attended and witness (by the angels) until the sun is directly overhead at midday, and that is the time when the gates of Hell are opened and it is stoked up. So do not pray until the shadows appear. Then prayer is attended and witnessed (by angels) until the sun sets, and it sets between the horns of a Shaitan, and that is the time when the disbelievers pray.'" (Using translation from Nasāʾī 572)
سَمِعْتُ عَمْرَو بْنَ عَبَسَةَ يَقُولُ قُلْتُ يَا رَسُولَ اللهِ هَلْ مِنْ سَاعَةٍ أَقْرَبَ مِنَ الْأُخْرَى أَوْ هَلْ سَاعَةٌ يُتَّقَى ذِكْرُهَا؟ قَالَ «نَعَمْ إِنَّ أَقْرَبَ مَا يَكُونُ الْعَبْدُ مِنَ الرَّبِّ جَوْفَ اللَّيْلِ الْآخِرِ فَإِنِ اسْتَطَعْتَ أَنْ تَكُونَ مِمَنْ يذْكُرُ اللهَ فِي تِلْكَ السَّاعَةِ فَكُنْ فَإِنَّ الصَّلَاةَ مَشْهُودَةٌ مَحْضُورَةٌ إِلَى طُلُوعِ الشَّمْسِ فَإِنَّهَا تَطْلُعُ بَيْنَ قَرْنَيْ شَيْطَانٍ وَهِيَ سَاعَةُ صَلَاةِ الْكُفَّارِ فَدَعِ الصَّلَاةَ حَتَّى تَرْتَفِعَ قِيدَ رُمْحٍ وَيَذْهَبَ شُعَاعُهَا ثُمَّ الصَّلَاةُ مَحْضُورَةٌ مَشْهُودَةٌ حَتَّى تَعْتَدِلَ الشَّمْسُ اعْتِدَالَ الرُّمْحِ بِنِصْفِ النَّهَارِ فَإِنَّهَا سَاعَةٌ تُفْتَحُ أَبْوَابُ جَهَنَّمَ وَتُسْجَرُ فَدَعِ الصَّلَاةَ حَتَّى يَفِيءَ الْفَيْءُ ثُمَّ الصَّلَاةُ مَحْضُورَةٌ مَشْهُودَةٌ حَتَّى تَغِيبَ الشَّمْسُ فَإِنَّهَا تَغِيبُ بَيْنَ قَرْنَيْ الشَّيْطَانِ وَهِيَ سَاعَةُ صَلَاةِ الْكُفَّارِ»
