The Muhajirin and Ansar as models of sacrifice

وَٱلسَّـٰبِقُونَ ٱلْأَوَّلُونَ مِنَ ٱلْمُهَـٰجِرِينَ وَٱلْأَنصَارِ وَٱلَّذِينَ ٱتَّبَعُوهُم بِإِحْسَـٰنٍ رَّضِىَ ٱللَّهُ عَنْهُمْ وَرَضُوا۟ عَنْهُ وَأَعَدَّ لَهُمْ جَنَّـٰتٍ تَجْرِى تَحْتَهَا ٱلْأَنْهَـٰرُ خَـٰلِدِينَ فِيهَآ أَبَدًا ۚ ذَٰلِكَ ٱلْفَوْزُ ٱلْعَظِيمُ

And the first forerunners [in the faith] among the Muhājireen and the Anṣār and those who followed them with good conduct - Allāh is pleased with them and they are pleased with Him, and He has prepared for them gardens beneath which rivers flow, wherein they will abide forever. That is the great attainment.
