Abu Hurairah (May Allah be pleased with him) reported:
A person came to Messenger of Allah ﷺ and asked, "Who among people is most deserving of my fine treatment?" He ﷺ said, "Your mother". He again asked, ''Who next?" "Your mother", the Prophet ﷺ replied again. He asked, "Who next?" He (the Prophet ﷺ) said again, "Your mother." He again asked, "Then who?" Thereupon he ﷺ said," Then your father."

In another narration: "O Messenger of Allah! Who is most deserving of my fine treatment?" He ﷺ said, "Your mother, then your mother, then your mother, then your father, then your nearest, then nearest".

[Al-Bukhari and Muslim].

وعنه رضي الله عنه قال: جاء رجل إلى رسول الله ﷺ فقال: يا رسول الله من أحق الناس بحسن صحابتي؟ قال: " أمك" قال: ثم من؟ قال: " أمك" قال: ثم من؟ قال: "أمك" قال: ثم من؟ قال: " أبوك" ((متفق عليه)). وفي رواية: يارسول الله من أحق بحسن الصحبة؟ قال: " أمك، ثم أمك، ثم أمك، ثم أباك، ثم أدناك أدناك".
