ḤADĪTH OF THE DAY

“ Messenger of God, peace and blessings of God be upon him, said to al-'Abbās, “My uncle, shall I not bestow [a gift] upon you? Shall I not give you something? Shall I not benefit you?” He replied, “Indeed, Messenger of God!” He said, “My uncle, pray four units of prayer, reciting in each unit 'The opening of the Book,' [1] and another chapter [of the Qur'ān]. Then, when the recitation is completed, say, 'God is the greatest; praise be to God; exalted be God; and there is no god but Allāh,' [2] fifteen times before you bow down. Then bow down and say it ten times. Then raise your head and say it ten times. Then prostrate and say it ten times. Then raise your head and say it ten times. Then prostrate for the second time and say it ten times. Then raise your head and say it ten times before you stand up. Those are seventy-five [utterances] in each unit of prayer, and three hundred in four units of prayer. Then, even if your sins were like dunes of sand, God will indeed forgive them for you.” He asked, “Messenger of God, who would be able to say that every day?” He replied, “If you are unable to say it every day, then say it once a week. If you are unable to say it once a week, then say it once a month.” He continued instructing him in this manner until he said, “Then, say it once a year.” Footnotes: 1: i.e. al-Fātiḥah, the first chapter of the Qur'ān. 2: Allāh is the Arabic name for the One and Only God, the same God shared by all monotheistic faiths (the name Allāh is often used by Arabic-speaking Christians and Jews). The name Allāh encompasses all the divine names and attributes of the Lord of the worlds, and hence has vast scope in meaning. It is for this reason that Muslims consider it unique. Unlike the word 'God', Allāh in Arabic has no inflections of gender or number. ”

حَدَّثَنَا هَارُونُ بْنُ إِسْحَاقَ الْهَمْدَانِىُّ حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُجَاوِرُ فِى الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ وَيَقُولُ تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِى الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ. وَفِى الْبَابِ عَنْ عُمَرَ وَأُبَىٍّ وَجَابِرِ بْنِ سَمُرَةَ وَجَابِرِ بْنِ عَبْدِ اللَّهِ وَابْنِ عُمَرَ وَالْفَلَتَانِ بْنِ عَاصِمٍ وَأَنَسٍ وَأَبِى سَعِيدٍ وَعَبْدِ اللَّهِ بْنِ أُنَيْسٍ وَأَبِى بَكْرَةَ وَابْنِ عَبَّاسٍ وَبِلاَلٍ وَعُبَادَةَ بْنِ الصَّامِتِ. قَالَ أَبُو عِيسَى حَدِيثُ عَائِشَةَ حَدِيثٌ حَسَنٌ صَحِيحٌ. وَقَوْلُهَا يُجَاوِرُ يَعْنِى يَعْتَكِفُ. وَأَكْثَرُ الرِّوَايَاتِ عَنِ النَّبِىِّ صلى الله عليه وسلم أَنَّهُ قَالَ الْتَمِسُوهَا فِى الْعَشْرِ الأَوَاخِرِ فِى كُلِّ وِتْرٍ. وَرُوِىَ عَنِ النَّبِىِّ صلى الله عليه وسلم فِى لَيْلَةِ الْقَدْرِ أَنَّهَا لَيْلَةُ إِحْدَى وَعِشْرِينَ وَلَيْلَةُ ثَلاَثٍ وَعِشْرِينَ وَخَمْسٍ وَعِشْرِينَ وَسَبْعٍ وَعِشْرِينَ وَتِسْعٍ وَعِشْرِينَ وَآخِرُ لَيْلَةٍ مِنْ رَمَضَانَ. قَالَ أَبُو عِيسَى قَالَ الشَّافِعِىُّ كَأَنَّ هَذَا عِنْدِى وَاللَّهُ أَعْلَمُ أَنَّ النَّبِىَّ صلى الله عليه وسلم كَانَ يُجِيبُ عَلَى نَحْوِ مَا يُسْأَلُ عَنْهُ يُقَالُ لَهُ نَلْتَمِسُهَا فِى لَيْلَةِ كَذَا فَيَقُولُ الْتَمِسُوهَا فِى لَيْلَةِ كَذَا. قَالَ الشَّافِعِىُّ وَأَقْوَى الرِّوَايَاتِ عِنْدِى فِيهَا لَيْلَةُ إِحْدَى وَعِشْرِينَ. قَالَ أَبُو عِيسَى وَقَدْ رُوِىَ عَنْ أُبَىِّ بْنِ كَعْبٍ أَنَّهُ كَانَ يَحْلِفُ أَنَّهَا لَيْلَةُ سَبْعٍ وَعِشْرِينَ. وَيَقُولُ أَخْبَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم بِعَلاَمَتِهَا فَعَدَدْنَا وَحَفِظْنَا. وَرُوِىَ عَنْ أَبِى قِلاَبَةَ أَنَّهُ قَالَ لَيْلَةُ الْقَدْرِ تَنْتَقِلُ فِى الْعَشْرِ الأَوَاخِرِ. حَدَّثَنَا بِذَلِكَ عَبْدُ بْنُ حُمَيْدٍ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ عَنْ مَعْمَرٍ عَنْ أَيُّوبَ عَنْ أَبِى قِلاَبَةَ بِهَذَا.
The Messenger of God, peace and blessings of God be upon him, used to take up residence nearby (1) during the last ten days of Ramaḍān and used to say, 'Seek the Glorious Night of Determination (2) during the last ten nights of Ramaḍān.'"
(1) i.e. he used to seclude himself in the mosque adjacent to his house, as a voluntary retreat for intensified worship. (2) The night during which the Qur'ān was first revealed to prophet Muhammad. It occurs on one of the last ten nights of Ramadan, though God only knows which. The Qur'ān states that on this night, God determines the course of the world and all human affairs for the coming year.
