Narrated Abu Wail: `Abdullah used to give a religious talk to the people on every Thursday. Once a man said, O Aba `Abdur-Rahman! (By Allah) I wish if you could preach us daily. He replied, The only thing which prevents me from doing so, is that I hate to bore you, and no doubt I take care of you in preaching by selecting a suitable time just as the Prophet used to do with us, for fear of making us bored.
