Hadith: Do not curse the rooster, for indeed it awakens (people) for prayer

عن زيد بن خالد الجُهني رضي الله عنه مرفوعاً: «لا تَسُبُّوا الدِّيْك فإنه يُوْقِظ للصلاة».
[صحيح] - [رواه أبو داود وأحمد والنسائي]

Zayd ibn Khālid al-Juhani (may Allah be pleased with him) reported the Prophet, may Allah's peace and blessings be upon him said: "Do not curse the rooster, for indeed it awakens (people) for prayer."
[Authentic hadith] - [An-Nasaa’i - Narrated by Abu Daoud - Narrated by Ahmad]

Explanation

Zayd ibn Khālid al-Juhany (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) forbade cursing the rooster because it awakens the sleeping person for prayer with its loud crow. Another narration by Imām Ahmad and An-Nasā’i reads: “It calls to prayer.” This is why the Prophet (may Allah's peace and blessings be upon him) forbade cursing the rooster, because there is a manifest benefit when it awakes people. It helps them carry out an act of obedience, and anyone supports others to carry out an act of obedience deserves praise, not blame. One of the most amazing things about the rooster is that it knows the nocturnal timings and crows in them. The rooster's crowing continues before dawn and after it. Glory be to the One who guided it to do that.
