وَعَن الْمُغيرَة بن شُعْبَة قا ل: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شِعَارُ الْمُؤْمِنِينَ يَوْمَ الْقِيَامَةِ عَلَى الصِّرَاطِ: رَبِّ سَلِّمْ سَلِّمْ ". رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيب
Al-Mughira b. Shu'ba reported God's messenger as saying, "On the day of resurrection the distinguishing sign of the believers on the Path will be, `My Lord, keep safe, keep safe'." Tirmidhi transmitted it, saying this is a gharib tradition.
