ٱلَّذِينَ يَتَرَبَّصُونَ بِكُمْ فَإِن كَانَ لَكُمْ فَتْحٌۭ مِّنَ ٱللَّهِ قَالُوٓا۟ أَلَمْ نَكُن مَّعَكُمْ وَإِن كَانَ لِلْكَٰفِرِينَ نَصِيبٌۭ قَالُوٓا۟ أَلَمْ نَسْتَحْوِذْ عَلَيْكُمْ وَنَمْنَعْكُم مِّنَ ٱلْمُؤْمِنِينَ ۚ فَٱللَّهُ يَحْكُمُ بَيْنَكُمْ يَوْمَ ٱلْقِيَٰمَةِ ۗ وَلَن يَجْعَلَ ٱللَّهُ لِلْكَٰفِرِينَ عَلَى ٱلْمُؤْمِنِينَ سَبِيلًا
Those who wait upon occasion in regard to you and, if a victory cometh unto you from Allah, say: Are we not with you? and if the disbelievers meet with a success say: Had we not the mastery of you, and did we not protect you from the believers? - Allah will judge between you at the Day of Resurrection, and Allah will not give the disbelievers any way (of success) against the believers.
Surah An-Nisaa(4:141)
