"O Messenger of Allah! Tell me of an action by which I may benefit.' He said: 'Remove harmful things from the path of the Muslims.'" (Using translation from Ibn Mājah 3681)
قُلْتُ يَا رَسُولَ اللهِ دُلَّنِي عَلَى عَمَلٍ يُدْخِلُنِي الْجَنَّةَ أَوْ أَنْتَفِعُ بِهِ؟ قَالَ اعْزِلِ الْأَذَى عَنْ طَرِيقِ الْمُسْلِمِينَ
