Arabic (Original)
حَدَّثَنَا عَبْد اللَّهِ حَدَّثَنَا أَبُو عَبْدِ اللَّهِ السُّلَمِيُّ قَالَ حَدَّثَنِي أَبُو دَاوُدَ عَنْ شُعْبَةَ عَنْ قَتَادَةَ قَالَ سَمِعْتُ أَنَسًا يَقُولُ انْشَقَّ الْقَمَرُ عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.
English Translation
The Messenger of Allah (peace be upon him) said: 'When one of you sneezes, let him say Al-hamdu lillah. And let his brother or companion say to him Yarhamukallah. When he says Yarhamukallah to him, let him respond: Yahdikumullahu wa yuslihu balakum (May Allah guide you and set right your affairs).'
