Narrated Al-Mughirah ibn Shu'bah:

I ate garlic and came to the place where the Prophet ﷺ was praying; one rak'ah of prayer had been performed when I joined. When I entered the mosque, the Prophet ﷺ noticed the odour of garlic.

When the Messenger of Allah ﷺ finished his prayer, he said: He who eats from this plant should not come near us until its odour has gone away.

When I finished the prayer, I came to the Messenger of Allah ﷺ and said: Messenger of Allah, do give me your hand. Then I put his hand in the sleeve of my shirt, carrying it to my chest to show that my chest was fastened with a belt. He said: You have a (valid) excuse.

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا أَبُو هِلاَلٍ، حَدَّثَنَا حُمَيْدُ بْنُ هِلاَلٍ، عَنْ أَبِي بُرْدَةَ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ أَكَلْتُ ثُومًا فَأَتَيْتُ مُصَلَّى النَّبِيِّ ﷺ وَقَدْ سُبِقْتُ بِرَكْعَةٍ فَلَمَّا دَخَلْتُ الْمَسْجِدَ وَجَدَ النَّبِيُّ ﷺ رِيحَ الثُّومِ فَلَمَّا قَضَى رَسُولُ اللَّهِ ﷺ صَلاَتَهُ قَالَ " مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ فَلاَ يَقْرَبْنَا حَتَّى يَذْهَبَ رِيحُهَا " . أَوْ " رِيحُهُ " . فَلَمَّا قَضَيْتُ الصَّلاَةَ جِئْتُ إِلَى رَسُولِ اللَّهِ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ وَاللَّهِ لَتُعْطِيَنِّي يَدَكَ . قَالَ فَأَدْخَلْتُ يَدَهُ فِي كُمِّ قَمِيصِي إِلَى صَدْرِي فَإِذَا أَنَا مَعْصُوبُ الصَّدْرِ قَالَ " إِنَّ لَكَ عُذْرًا " .
