Abdullah bin Abbas reported,

Regarding the verse "If you do not march forth, He will punish you with a painful punishment" [Tawbah 9:39], and the verses from "It was not for the people of Madinah" up to His statement "what they used to do" [Tawbah 9:120–121], these were abrogated by the verse that follows them, "And the believers should not all go forth to fight" [Tawbah 9:122].

عن ابن عباس قال

{إلا تنفروا يعذبكم عذابا} {ما كان لأهل المدينة} إلى قوله: {يعملون} نسختها الآية التي تليها {وما كان المؤمنون لينفروا كافة}
