Narrated Abu Hurayrah رضي الله عنه : Abul Qasim ﷺ said: When one of you is in the sun (Shams) and the shadow withdraws from him so that he is partly in the sun and partly in the shade, he should get up. What is the ruling related to this Hadith ? Is it Haram or only Makrooh? Also can we apply this ruling to the shade due to artificial lights?
