Hadith 869
Abu Wa'il reported: 'Ammar delivered to us the sermon. It was short and eloquent. When he ('Ammar) descended (from the pulpit) we said to him: O Abdul Yaqzn, you have delivered a short and eloquent sermon. Would that you had lengthened (the sermon). He said: I have heard the Messenger of Allah (ﷺ) as saying: The lengthening of prayer by a man and the shortness of the sermon is the sign of his understanding (of faith). So lengthen the prayer and shorten the sermon, for there is charm (in precise) expression.
Hadith 996
Khaithama reported: While we were sitting in the company of 'Abdullah bin 'Umar there came in his steward. He (Ibn 'Umar) said: Have you supplied the provision to the slaves? He said: No. Upon this he said: Go and give (the provision) to them, for the Messenger of Allah (ﷺ) has said: This sin is enough for a man that he withholds the subsistence from one whose master he is.
