Your mother, then your mother, then your mother
جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ: يَا رَسُولَ اللَّهِ، مَنْ أَحَقُّ النَّاسِ بِحُسْنِ صَحَابَتِي؟ قَالَ: أُمُّكَ. قَالَ: ثُمَّ مَنْ؟ قَالَ: أُمُّكَ. قَالَ: ثُمَّ مَنْ؟ قَالَ: أُمُّكَ. قَالَ: ثُمَّ مَنْ؟ قَالَ: أَبُوكَ
Ja'a rajulun ila rasuli-llahi sallallahu alayhi wa sallam fa-qala: Ya rasula-llah, man ahaqqu-n-nasi bi-husni sahabati? Qala: Ummuk. Qala: Thumma man? Qala: Ummuk. Qala: Thumma man? Qala: Ummuk. Qala: Thumma man? Qala: Abuk.
"A man came to the Messenger of Allah ﷺ and said: O Messenger of Allah, who among people is most deserving of my good companionship? He said: Your mother. He said: Then who? He said: Your mother. He said: Then who? He said: Your mother. He said: Then who? He said: Your father."
Narrated by Abu Hurayrah. Sahih al-Bukhari 5971, Sahih Muslim 2548
A short reflection
The math is plain. Three to one. The mother carried, gave birth, nursed; the father provided. Both honoured, but the weight asked of her is the weight named first.
