عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ قَالَ: زَعَمَ ثَابِتُ بْنُ الضَّحَّاكِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنِ الْمُزَارَعَةِ وَأَمَرَ بِالْمُؤَاجَرَةِ وَقَالَ: «لَا بَأْسَ بِهَا» . رَوَاهُ مُسْلِمٌ
Translation

Ibn ‘Abbas said the Prophet had himself cupped and gave the cupper his pay; and he poured medicine into his nose. (Bukhari and Muslim.)
