Mukhtasar Bukhari

`Sayyiduna Ibn Abbas (may Allah be pleased with them both)` once delivered the Friday sermon on a rainy day, and when the muezzin reached "Hayya 'ala-s-Salah," he instructed him to say, "As-salatu fi ar-rihal" (Perform the prayer at your places). So the people began to look at each other, as if they disliked it. Then Sayyiduna Ibn Abbas (may Allah be pleased with them both) said, "It seems that you have disliked this. Indeed, this was done by one who is better than me, meaning the Noble Prophet (peace and blessings of Allah be upon him). Indeed, Jumu'ah is obligatory, but I did not like that I should put you in hardship (that you should come treading mud up to your knees)."
