Muhajir came to the Prophet ﷺ while he was urinating. He saluted him. The Prophet ﷺ did not return the salutation to him until he performed ablution. He then apologised to him, saying: I disliked remembering Allah except in the state of purification.  

أَنَّهُ أَتَى النَّبِيَّ ﷺ وَهُوَ يَبُولُ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ حَتَّى تَوَضَّأَ ثُمَّ اعْتَذَرَ إِلَيْهِ فَقَالَ إِنِّي كَرِهْتُ أَنْ أَذْكُرَ اللَّهَ ﷻ إِلاَّ عَلَى طُهْرٍ أَوْ قَالَ عَلَى طَهَارَةٍ  

[Machine] About a man who greeted him while he was not in a state of ritual purity. So he (the Prophet) said: Sa'eed narrated to us from Qatadah from Al-Hasan from Al-Hudhayn, the father of Sasanah, from Al-Muhajir bin Qunfudh that he greeted the Messenger of Allah ﷺ while he was performing ablution, and he did not respond to him until he completed his ablution. Then he responded to him and said: "I did not hesitate to respond to you except that I disliked mentioning Allah except in a state of purity."  

عَنْ رَجُلٍ يُسَلِّمُ عَلَيْهِ وَهُوَ غَيْرُ مُتَوَضِّئٍ؟ فَقَالَ حَدَّثَنَا سَعِيدٌ عَنْ قَتَادَةَ عَنِ الْحَسَنِ عَنِ الْحُضَيْنِ أَبِي سَاسَانَ عَنِ الْمُهَاجِرِ بْنِ قُنْفُذٍ أَنَّهُ سَلَّمَ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ يَتَوَضَّأُ فَلَمْ يَرُدَّ عَلَيْهِ حَتَّى تَوَضَّأَ فَرَدَّ عَلَيْهِ وَقَالَ إِنَّهُ لَمْ يَمْنَعْنِي أَنْ أَرُدَّ عَلَيْكَ إِلَّا أَنِّي كَرِهْتُ أَنْ أَذْكُرَ اللهَ إِلَّا عَلَى طَهَارَةٍ  

[Machine] Juda'an reported that he greeted the Messenger of Allah ﷺ while he was performing ablution but the Messenger of Allah ﷺ did not reply to him. When he finished his ablution, the Messenger of Allah ﷺ said, "I did not respond to you because I disliked mentioning Allah except in a state of purity."  

جُدْعَانَأَنَّهُ سَلَّمَ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ يَتَوَضَّأُ فَلَمْ يَرُدَّ عَلَيْهِ فَلَمَّا فَرَغَ مِنْ وُضُوئِهِ قَالَ إِنَّهُ لَمْ يَمْنَعْنِي أَنْ أَرُدَّ عَلَيْكَ إِلَّا أَنِّي كَرِهْتُ أَنْ أَذْكُرَ اللهَ إِلَّا عَلَى طَهَارَةٍ  

[Machine] I passed by the Messenger of Allah ﷺ while he was performing ablution. I greeted him, but he did not respond to me. When he finished, he responded and apologized to me, saying, "It was not that I prevented myself from responding to you except that I disliked mentioning Allah while I was in a state of impurity."  

مَرَرْتُ بِرَسُولِ اللهِ ﷺ فَسَلَّمْتُ وَهُوَ يَتَوَضَّأُ فَسَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ فَلَمَّا فَرَغَ رَدَّ عَلَيَّ واعْتَذَرَ إِلَيَّ وَقَالَ «إِنْهُ لَمْ يَمْنَعْنِي أَنْ أَرُدَّ عَلَيْكَ إِلَّا أَنِّي كَرِهْتُ أَنْ أَذْكُرَ اللهَ وَأَنَا عَلَى غَيْرِ طَهَارَةٍ»  

[Machine] He greeted the Messenger of Allah ﷺ while he was performing ablution, but he did not respond to him. So, when he finished his ablution, he said, "The only reason I did not respond to you was because I disliked remembering Allah except in a state of purity."  

أَنَّهُ سَلَّمَ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ يَتَوَضَّأُ فَلَمْ يَرُدَّ عَلَيْهِ فَلَمَّا فَرَغَ مِنْ وُضُوئِهِ قَالَ إِنَّهُ لَمْ يمْنَعْنِي أَنْ أَرُدَّ عَلَيْكَ إِلَّا أَنِّي كَرِهْتُ أَنْ أَذْكُرَ اللهَ إِلَّا عَلَى طَهَارَةٍ  

"إِنَّهُ لَمْ يَمْنَعنِى أَنْ أَرُدَّ عَلَيْكَ إِلَّا أنِّى كُنْتُ على غَيْرِ وُضوءٍ، وفى لفظ: إِلَّا أَنى كرهْتُ أَن أَذكُرَ اللَّه وأَنا على غير طُهُورٍ ".
