Proof of conveying reward from blessed Aḥādīth

The mother of the believers, Sayyidatunā ꜤĀˈishah al-Ṣiddīqah رَضِیَ الـلّٰـهُ عَنْهَا has narrated that the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم ordered:

A horned ram should be brought that walks in darkness, sits in darkness and sees in darkness (meaning, its feet, belly and eyes should be dark.) When it was presented to be sacrificed, the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, “ꜤĀˈishah, bring me a knife and sharpen it on a stone.” Then the Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم took the knife and slaughtered the ram after making it lie down. He صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم then said, “O Allah Almighty! Accept it on behalf of Muhammad (صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم), his offspring and his Ummah.”^[1]

Commenting on this hadith, Mufti Aḥmad Yār Khan NāꜤīmī رَحْمَةُ الـلّٰـهِ عَـلَيْه has said:

Meaning. also include them amongst those who get the reward of Qurbani. From this it has been learnt that we can convey the reward of our Fard and Wajib acts to others, and nothing will be reduced from [the reward in this way].This blessed hadith is a very strong evidence of conveying reward of the food which we place in front of us, as the goat was in front of our Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم and he صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم conveyed its reward to his offspring and Ummah.^[2]

The Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم would often talk about Sayyidatunā Khadījah رَضِیَ الـلّٰـهُ عَنْهَا and sometimes after slaughtering a goat, he صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم would cut its meat into pieces and then send it to the friends of Sayyidatunā Khadījah رَضِیَ الـلّٰـهُ عَنْهَا.^[3]

Mufti Aḥmad Yār Khan NāꜤīmī رَحْمَةُ الـلّٰـهِ عَـلَيْه writes:

The Beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم would often sacrifice a goat on behalf of the mother of the believers, Sayyidatunā Khadījah رَضِیَ الـلّٰـهُ عَنْهَا and would distribute its meat to her friends for conveying reward to her.
