وَعَنْ عَلِيَّ بْنَ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كُنْتُ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِمَكَّةَ فَخَرَجْنَا فِي بَعْضِ نَوَاحِيهَا فَمَا اسْتَقْبَلَهُ جَبَلٌ وَلَا شَجَرٌ إِلَّا وَهُوَ يَقُولُ: السَّلَامُ عَلَيْكَ يَا رَسُولَ اللَّهِ. رَوَاهُ التِّرْمِذِيّ والدارمي
`Ali b. Abu Talib said:Once when I was with the Prophet in Mecca and we went out into one of its districts in the neighbourhood, not a mountain or tree which confronted him failed to say, "Peace be upon you, messenger of God." Tirmidhi and Darimi transmitted it.
