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 مُحَمَّدُ بْنُ حُمَيْدٍ حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ وَأَبُو تُمَيْلَةَ يَحْيَى بْنُ وَاضِحٍ عَنْ عَبْدِ اللَّهِ بْنِ مُسْلِمٍ عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ عَنْ أَبِيهِ قَالَ جَاءَ رَجُلٌ إِلَى النَّبِىِّ صلى الله عليه وسلم وَعَلَيْهِ خَاتَمٌ مِنْ حَدِيدٍ فَقَالَ مَا لِى أَرَى عَلَيْكَ حِلْيَةَ أَهْلِ النَّارِ. ثُمَّ جَاءَهُ وَعَلَيْهِ خَاتَمٌ مِنْ صُفْرٍ فَقَالَ مَا لِى أَجِدُ مِنْكَ رِيحَ الأَصْنَامِ. ثُمَّ أَتَاهُ وَعَلَيْهِ خَاتَمٌ مِنْ ذَهَبٍ فَقَالَ مَالِى أَرَى عَلَيْكَ حِلْيَةَ أَهْلِ الْجَنَّةِ. قَالَ مِنْ أَىِّ شَىْءٍ أَتَّخِذُهُ قَالَ مِنْ وَرِقٍ وَلاَ تُتِمَّهُ مِثْقَالاً. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ غَرِيبٌ. وَفِى الْبَابِ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو. وَعَبْدُ اللَّهِ بْنُ مُسْلِمٍ يُكْنَى أَبَا طَيْبَةَ وَهُوَ مَرْوَزِىٌّ.
A man came to the Prophet, peace and blessings of God be upon him, wearing an iron ring, so he (the Prophet) said, "Why do I see you wearing the ornament of the people of the Fire? (1)" He then came wearing a copper ring, so the Prophet, peace and blessings of God be upon him, asked, "Why is the smell of idols emanating from you? (2)" Then he came wearing a gold ring, so the Prophet, peace and blessings of God be upon him asked, "Why do I see you wearing the adornment of the people of Paradise? (3)". The man (then) asked, "What should it be made of?" He replied, "Silver, but less than a mithqāl (4) (5)".
(1) Referring to the iron rings that the disbelievers used to wear, or to the chains of the people of the Fire that are also made of iron. (2) As idols were generally made from copper. (3) Men are not permitted to wear gold, but it will be permissible for them in Paradise. (4) Mithqāl: A unit of weight, usually used to measure gold, equivalent to 4.6 grams or 4.2 grams, but it is generally considered equivalent to 5 grams for simplicity. (5) Most scholars find wearing a silver ring that weighs more than a mithqāl permissible for men based on other evidence.
