Who is the "Capable Person" for whom the Udhiyah is recommended?
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
The "Capable Person" (Al-Qadir): This refers to anyone who possesses surplus wealth beyond their own essential needs and the financial maintenance of their wife, children, or whoever is under their legal care, during the day of Eid and the three days of Tashreeq (the 11th, 12th, and 13th of Dhul-Hijjah), as this is the designated timeframe for the sacrifice. And Allah Knows Best.
Is it permissible to offer mandatory prayer while sitting?
All perfect praise be to Allah, The Lord of The Worlds, and may His Peace and Blessings be upon our Prophet Muhammad and upon all of his family and companions. Standing up is a pillar in the mandatory prayer and the prayer is not valid without it unless one cannot do it. As for Nafila (supererogatory prayer), one can perform it in the state of sitting even if he/she can stand, but his/her reward is half the reward of the person who prays while standing if he/sh has no legal excuse for such an act. And Allah Knows Best.
What is the ruling on performing dry ablution (tayammum) on a wall or stone?
One of the conditions for tayammum is that it be with pure, clean dust (soil). It is not valid to perform tayammum by striking stones, a wall, sand that has no dust (i.e., that does not produce dust), pebbles alone, or clay, as these are not from the earth or its same category. And Allah the Almighty knows best.
