Nahj al-Balāgha

Hadith 1861
brotherhoodtaqwa
فَعَلَيْكُمْ بِهَذِهِ الْخَلَائِقِ فَالْزَمُوهَا وَتَنَافَسُوا فِيهَا فَإِنْ لَمْ تَسْتَطِيعُوهَا فَاعْلَمُوا أَنَّ أَخْذَ الْقَلِيلِ خَيْرٌ مِنْ تَرْكِ الْكَثِيرِ.
These qualities are incumbent upon you. So, you should acquire them and excel each other in them. Even if you cannot acquire them you should know that acquiring a part is better than giving up the whole.
