Abu Jamra reported,

I used to sit with Ibn Abbas, and he would seat me on his couch. He said to me, "Stay with me, and I will give you a share of my wealth." So I stayed with him for two months.Then he said, "When the delegation of Abdul-Qays came to the Prophet ﷺ, he asked, 'Who are these people?' or 'Who is the delegation?'They replied, 'We are from Rabia.'He said, 'Welcome to the people,' or 'to the delegation, neither disgraced nor regretful.'They said, 'Messenger of Allah, we are unable to come to you except during the sacred month, for between us and you stands this tribe of the disbelievers of Mudar. So instruct us with a clear command that we may convey to those we left behind and by which we may enter Paradise.'They also asked him about drinks. He commanded them with four things and forbade them four things. He commanded them with faith in Allah alone, then said, 'Do you know what faith in Allah alone is?'They said, 'Allah and His Messenger know best.'He said, 'It is the testimony that there is no god but Allah and that Muhammad is the Messenger of Allah, establishing the prayer, giving the zakat, fasting Ramadan, and that you give one-fifth of the war spoils.'And he forbade them four things, the hantam, the dubba, the Naqi, and the muzaffat,' and perhaps he said, 'the muqayyar.' He said, 'Memorize these things and inform those you left behind of them.'"

عن أبي جمرة قال

كنت أقعد مع ابن عباس يجلسني على سريره فقال: أقم عندي حتى أجعل لك سهما من مالي. فأقمت معه شهرين، ثم قال: إن وفد عبد القيس لما أتوا النبي ﷺ قال: من القوم؟ - أو من الوفد؟ - قالوا: ربيعة. قال: مرحبا بالقوم- أو بالوفد- غير خزايا ولا ندامى. فقالوا: يا رسول الله، إنا لا نستطيع أن نأتيك إلا في الشهر الحرام وبيننا وبينك هذا الحي من كفار مضر، فمرنا بأمر فصل نخبر به من وراءنا، وندخل به الجنة. وسألوه عن الأشربة، فأمرهم بأربع، ونهاهم عن أربع، أمرهم: بالإيمان بالله وحده، قال: أتدرون ما الإيمان بالله وحده؟ قالوا: الله ورسوله أعلم. قال: شهادة أن لا إله إلا الله وأن محمدا رسول الله، وإقام الصلاة، وإيتاء الزكاة، وصيام رمضان، وأن تعطوا من المغنم الخمس. ونهاهم عن أربع: عن الحنتم والدباء والنقير، والمزفت، وربما قال: المقير، وقال: احفظوهن وأخبروا بهن من وراءكم.
