Sahih al-Bukhari 344
In-book no 344حَدَّثَنَا عَبْدَانُ، قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ، قَالَ أَخْبَرَنَا عَوْفٌ، عَنْ أَبِي رَجَاءٍ، قَالَ حَدَّثَنَا عِمْرَانُ بْنُ حُصَيْنٍ الْخُزَاعِيُّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى رَجُلاً مُعْتَزِلاً لَمْ يُصَلِّ فِي الْقَوْمِ فَقَالَ " يَا فُلاَنُ مَا مَنَعَكَ أَنْ تُصَلِّيَ فِي الْقَوْمِ ". فَقَالَ يَا رَسُولَ اللَّهِ، أَصَابَتْنِي جَنَابَةٌ وَلاَ مَاءَ. قَالَ " عَلَيْكَ بِالصَّعِيدِ فَإِنَّهُ يَكْفِيكَ ".
Narrated `Imran bin Husain Al-Khuza`i: Allah's Messenger (ﷺ) saw a person sitting aloof and not praying with the people. He asked him, "O so and so! What prevented you from offering the prayer with the people?" He replied, "O Allah's Messenger (ﷺ)! I am Junub and there is no water." The Prophet (ﷺ) said, "Perform Tayammum with clean earth and that will be sufficient for you."
