English translation
603. It was narrated from Ibn 'Abbâs that the Prophet ﷺ used to pray in Al-Madīnah combining two prayers. Joining Zuhr and ‘Asr, and Maghrib and ‘Ishâ’, when there was no fear nor rain. It was said to him: “Why?” He said: “So that there would not be any hardship on his Ummah.” (Sahīh)
