I heard my father say, "A companion of mine and I went to Ibn Abbas. We met Abu Hurayrah at the door of Ibn Abbas, and he asked, 'Who are you two?'We told him.He said, 'Go to a people who have dates and water. Every valley flows according to its capacity.'I said, 'May your good increase. Seek permission for us to enter upon Ibn Abbas.'So he sought permission for us, and we heard Ibn Abbas narrating from the Messenger of Allah ﷺ. He said, 'The Messenger of Allah ﷺ delivered a sermon on the day of Tabuk and said, "There is no one among the people like a man who takes hold of his horse's reins and strives in the path of Allah while avoiding the evils of people, and like a man who lives in the desert with his sheep, offers hospitality to his guest, and gives what is due from them."'I asked, 'Did he really say that?'He replied, 'He said it.'I asked again, 'Did he really say that?'He replied, 'He said it.'I asked once more, 'Did he really say that?'He replied, 'He said it.'So I declared the greatness of Allah, praised Allah, and gave thanks."
حدثنا روح حدثنا
سمعت أبي يقول أتيت ابن عباس أنا وصاحب لي فلقينا أبا هريرة عند باب ابن عباس فقال من أنتما فأخبرناه فقال انطلقا إلى ناس على تمر وماء إنما يسيل كل واد بقدره قال قلنا كثر خيرك استأذن لنا على ابن عباس قال فاستأذن لنا فسمعنا ابن عباس يحدث عن رسول الله ﷺ فقال خطب رسول الله ﷺ يوم تبوك فقال ما في الناس مثل رجل أخذ بعنان فرسه فيجاهد في سبيل الله ويجتنب شرور الناس ومثل رجل باد في غنمه يقري ضيفه ويؤدي حقه قال قلت أقالها قال قالها قال قلت أقالها قال قالها قال قلت أقالها قال قالها فكبرت الله وحمدت الله وشكرت
Its isnad is sahih, and it is a longer version of 1987. As for Abu Hurairah's statement, "Let us go," and so on, he is inviting them to his hospitality of water and dates, apologizing for the little he can offer them, for he is generous with whatever he has.
