The companions of Messenger of Allah ﷺ used to practice manual labor, so their sweat used to smell, and they were advised to take a bath. (Using translation from Bukhārī 2071)   

عَائِشَةُ كَانَ أَصْحَابُ رَسُولِ اللهِ ﷺ قَوْمًا عُمَّالَ أَنْفُسِهِمْ وَكَانَ يَكُونُ لَهُمْ أَرْوَاحٌ فَقِيلَ لَهُمْ لَوِ اغْتَسَلْتُمْ  

He heard Al-Qasim bin Muhammad bin Abi Bakr (say) that they mentioned Ghusl on Fridays in the presence of 'Aishah and she said: "Some people used to live in Al-'Aliyah and they would come to Jumu'ah with dirt on them (because of their work). When a breeze came it would carry their smell to the people which annoyed them. Mention of that was made to the Messenger of Allah ﷺ and he said: "Why don't you perform Ghusl?" (Using translation from Nasāʾī 1379)  

إِنَّمَا كَانَ النَّاسُ يَسْكُنُونَ الْعَالِيَةَ فَيَحْضُرُونَ الْجُمُعَةَ وَبِهِمْ وَسَخٌ وَإِذَا أَصَابَهُمُ الرَّوْحُ سَطَعَتْ أَرْوَاحُهُمْ فَيَتَأَذَّى بِهِمُ النَّاسُ فَذُكِرَ ذَلِكَ لِرَسُولِ اللهِ ﷺ فَقَالَ «أَوَلَا يَغْتَسِلُونَ؟»
