عَنْ عَمْرِو بْنِ عَبَسَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((صَلَاةُ اللَّيْلِ مَثْنَى مَثْنَى، وَجَوْفُ اللَّيْلِ الْآخِرُ أَجْوَبُهُ دَعْوَةً))، قُلْتُ: أَوْجَبُهُ؟ قَالَ: ((لَا، بَلْ أَجْوَبُهُ)) يَعْنِي بِذَلِكَ الإِجَابَةَ
Sayyiduna Amr bin Abasah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: The night prayer is in sets of two rak‘ahs, and in the last (third) part of the night, supplication is most readily accepted. I asked: Is it obligatory to supplicate in that part? He (peace and blessings be upon him) said: No, no, (I am saying that) supplication is most readily accepted. His (peace and blessings be upon him) intent was acceptance.
