Some reminders mentioned in Khutbah by Imam Dr. Shaheed Coovadia for pondering:

48:28

هُوَ ٱلَّذِىٓ أَرْسَلَ رَسُولَهُۥ بِٱلْهُدَىٰ وَدِينِ ٱلْحَقِّ لِيُظْهِرَهُۥ عَلَى ٱلدِّينِ كُلِّهِۦ ۚ وَكَفَىٰ بِٱللَّهِ شَهِيدًۭا ٢٨

He is the One Who has sent His Messenger with ˹right˺ guidance and the religion of truth, making it prevail over all others. And sufficient is Allah as a Witness.

— Dr. Mustafa Khattab, the Clear Quran

Abu Qatadah narrated that :

the Prophet said: "Fast the Day of Ashura, for indeed I anticipate that Allah will forgive (the sins of) the year before it."

It was narrated that Ibn ‘Abbas said:

“The Prophet (ﷺ) came to Al- Madinah, and he found the Jews observing a fast. He said: ‘What is this?’ They said: ‘This is the day when Allah saved Musa and drowned Pharaoh, so Musa fasted this day in gratitude.’ The Messenger of Allah (ﷺ) said: ‘We have more right to Musa than you do.’ So he fasted (that day) and enjoined (others) to fast it also.’”

2:193

وَقَـٰتِلُوهُمْ حَتَّىٰ لَا تَكُونَ فِتْنَةٌۭ وَيَكُونَ ٱلدِّينُ لِلَّهِ ۖ فَإِنِ ٱنتَهَوْا۟ فَلَا عُدْوَٰنَ إِلَّا عَلَى ٱلظَّـٰلِمِينَ ١٩٣

Fight against them ˹if they persecute you˺ until there is no more persecution, and ˹your˺ devotion will be to Allah ˹alone˺. If they stop ˹persecuting you˺, let there be no hostility except against the aggressors.

— Dr. Mustafa Khattab, the Clear Quran
