وَمَا ظَلَمْنَٰهُمْ وَلَٰكِن ظَلَمُوٓا۟ أَنفُسَهُمْ ۖ فَمَآ أَغْنَتْ عَنْهُمْ ءَالِهَتُهُمُ ٱلَّتِى يَدْعُونَ مِن دُونِ ٱللَّهِ مِن شَىْءٍۢ لَّمَّا جَآءَ أَمْرُ رَبِّكَ ۖ وَمَا زَادُوهُمْ غَيْرَ تَتْبِيبٍۢ
We wronged them not, but they did wrong themselves; and their gods on whom they call beside Allah availed them naught when came thy Lord's command; they added to them naught save ruin.
Surah Hud(11:101)
Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: The service, during holy battles
Narrated Anas bin Malik:
I went along with the Prophet (ﷺ) to Khaibar so as to serve him. (Later on) when the Prophet (ﷺ) returned he, on seeing the Uhud mountain, said, "This is a mountain that loves us and is loved by us." Then he pointed to Medina with his hand saying, "O Allah! I make the area which is in between Medina's two mountains a sanctuary, as Abraham made Mecca a sanctuary. O Allah! Bless us in our Sa` and Mudd (i.e. units of measuring)."
