 أَبِی ره قَالَ حَدَّثَنِی سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ أَبِی عَبْدِ اللَّهِ عَنْ أَبِیهِ عَنْ حَمَّادِ بْنِ عِیسَی عَنْ إِبْرَاهِیمَ بْنِ عُمَرَ الْیَمَانِیِّ عَنْ أَبِی عَبْدِ اللَّهِ ع قَالَ: مَا مِنْ مُؤْمِنٍ یُعِینُ مُؤْمِناً مَظْلُوماً إِلَّا کَانَ أَفْضَلَ مِنْ صِیَامِ شَهْرٍ وَ اعْتِکَافِهِ فِی الْمَسْجِدِ الْحَرَامِ وَ مَا مِنْ مُؤْمِنٍ یَنْصُرُ أَخَاهُ وَ هُوَ یَقْدِرُ عَلَی نُصْرَتِهِ إِلَّا وَ نَصَرَهُ اللَّهُ فِی الدُّنْیَا وَ الْآخِرَهِ وَ مَا مِنْ مُؤْمِنٍ یَخْذُلُ أَخَاهُ وَ هُوَ یَقْدِرُ عَلَی نُصْرَتِهِ إِلَّا خَذَلَهُ اللَّهُ فِی الدُّنْیَا وَ الْآخِرَهِ.
1. My father (rah) said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Abi Abdillah from his father from Hamad b. Isa from Ibrahim b. Umar al-Yamani from Abi Abdillah  who said: “One who helps an oppressed believer its reward is better than that of fasting for a month and performing Etekaf in Masjidul Haraam. One who is capable of helping a Muslim and helps him, the Almighty Allah will help him in the world and the hereafter. If a believer is being backbited and a person capable of helping him remains silent and does not defend him, the Almighty Allah will make him deprived in the world and the hereafter.”
