[Machine] "Allah, the Blessed and Exalted, said, 'Take your precautions and march forth in groups or altogether.' (Surah An-Nisa 71) And He said, 'March forth, light and heavy.' (Surah At-Tawbah 41) And He said, 'If you do not march forth, He will punish you with a painful punishment.' (Surah At-Tawbah 39) Then, He abrogated these verses and said, 'And it is not for the believers to march forth all together.' (Surah At-Tawbah 122) He said, so a group went out with the Messenger of Allah ﷺ and another group stayed behind. He said, 'Those who stay behind with the Messenger of Allah ﷺ are the ones who study and teach the religion and warn their people when they return from the expedition, so that they may be cautious about what Allah has revealed from His book, its obligations, and its limits.'"
