وَعَنْ أَبِي سَعِيدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِعَلِيٍّ: «يَا عَلِيُّ لَا يَحِلُّ لِأَحَدٍ يُجْنِبُ فِي هَذَا الْمَسْجِدِ غَيْرِي وَغَيْرَكَ» قَالَ عَلِيُّ بْنُ الْمُنْذِرِ: فَقُلْتُ لِضِرَارِ بْنِ صُرَدٍ: مَا مَعْنَى هَذَا الْحَدِيثِ؟ قَالَ: لَا يَحِلُّ لِأَحَدٍ يَسْتَطْرِقُهُ جُنُبًا غَيْرِي وَغَيْرَكَ. رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ

Abu Sa’id told that God’s messenger said to `Ali, “It is not allowable, `Ali, for anyone but you or me to be in a state of ceremonial impurity in this mosque.” `Ali b. al-Mundhir told that be asked Dirar b. Surad what was the meaning of this tradition, and he replied that the meaning was, “It is not allowable for anyone but you or me to walk through it in a state of ceremonial impurity.” Tirmidhi transmitted it, saying this is a hasan gharib tradition.
