Hadith 1730
Zaid bin Khalid Al-Juhani (May Allah be pleased with him) said:
عن زيد بن خادل الجهني رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : "لا تسبوا الديك، فإنه يوقظ للصلاة" .(( رواه أبو داود بإسناد صحيح))
The Messenger of Allah (ﷺ) said, "Do not revile the rooster for it wakes you up for prayer." [Abu Dawud].
In plain words
Do not curse the rooster, for its crow wakes people for prayer. Even a humble creature can carry quiet good, so guard the tongue from careless reviling.
