Narrated Ibn `Abbas:A delegation of the tribe of `Abdul Qais came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! We are from the tribe of Rabi`a, and the infidels of the tribe of Mudar stands between us and you; so we cannot come to you except during the Sacred Months. Please order us to do something (religious deeds) which we may carry out and also invite to it our people whom we have left behind." The Prophet said, "I order you to do four things and forbid you four others: (I order you) to have faith in Allah, and confess that none has the right to be worshipped but Allah, (and the Prophet (ﷺ) gestured with his hand like this (i.e. one knot) and to offer prayers perfectly and to pay the Zakat, and to pay onefifth of the booty in Allah's Cause. And I forbid you to use Dubba', Hantam, Naqir and Muzaffat (all these are the names of utensils used for preparing alcoholic drinks)."
حَدَّثَنَا حَجَّاجٌ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا أَبُو جَمْرَةَ، قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ يَقُولُ قَدِمَ وَفْدُ عَبْدِ الْقَيْسِ عَلَى النَّبِيِّ صلى الله عليه وسلم فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّ هَذَا الْحَىَّ مِنْ رَبِيعَةَ قَدْ حَالَتْ بَيْنَنَا وَبَيْنَكَ كُفَّارُ مُضَرَ، وَلَسْنَا نَخْلُصُ إِلَيْكَ إِلاَّ فِي الشَّهْرِ الْحَرَامِ، فَمُرْنَا بِشَىْءٍ نَأْخُذُهُ عَنْكَ، وَنَدْعُو إِلَيْهِ مَنْ وَرَاءَنَا. قَالَ " آمُرُكُمْ بِأَرْبَعٍ، وَأَنْهَاكُمْ عَنْ أَرْبَعٍ الإِيمَانِ بِاللَّهِ وَشَهَادَةِ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ ـ وَعَقَدَ بِيَدِهِ هَكَذَا ـ وَإِقَامِ الصَّلاَةِ، وَإِيتَاءِ الزَّكَاةِ، وَأَنْ تُؤَدُّوا خُمُسَ مَا غَنِمْتُمْ، وَأَنْهَاكُمْ عَنِ الدُّبَّاءِ وَالْحَنْتَمِ وَالنَّقِيرِ وَالْمُزَفَّتِ ". وَقَالَ سُلَيْمَانُ وَأَبُو النُّعْمَانِ عَنْ حَمَّادٍ " الإِيمَانِ بِاللَّهِ شَهَادَةِ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ ".
