وَعَن أبي أُسَيدٍ الْأَنْصَارِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : كَلُوا الزَّيْتَ وَادَّهِنُوا بِهِ فَإِنَّهُ مِنْ شَجَرَةٍ مُبَارَكَةٍ
رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ وَالدَّارِمِيُّ
Meaning:
Abu Usaid al-Ansari reported the messenger of Allah صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ as saying, “Have olive oil and use yourselves with it as it comes from a blessed tree.”
Tirmidhi, Ibn Majah and Darimi transmitted it
