What is the difference between Tahajjud prayer and night prayer, and do they have a particular Witr prayer other than that of Isha (evening prayer)?
Tahajjud and Qiyam-Al-Lail (night prayer) are two words for the same meaning which is offering voluntary prayer at night after sunset, but before dawn break. However, Tahajjud is offered after waking up; whereas, Qiyam-Al-Lail is permissible before sleeping, or after it. Therefore, every Tahajjud is a Qiyam, but not every Qiyam is a Tahajjud. Moreover, there is no specified Witr for both of them, but Witr after Isha is by itself the Witr of Qiyam, and it is a Sunnah to postpone it until after Qiyam if the worshiper thought that he was most probably going to wake up in order to offer it, but if he wasn`t sure of waking up, then he is at liberty to offer it before going to bed as was reported in the Prophet`s Hadith.
Is it permissible for the wife to give the Zakah (obligatory charity) of her money to her poor husband?

Is buying shared land from someone who has taken possession of it considered halal or haram?
The shared land is possessed by the country i.e. for all people; therefore, it shouldn't be possessed/occupied save by it's guardian/owner permission,thusly it can't be possessed save by having owners' permission. Finally, buying it from a person who don't possess it is impermissible. And Allah Knows Best.
A woman died at the age of ninety. Her living children are nine: two sons and two daughters. The youngest of her grandchildren, from her son who passed away one year before her, is aged thirty-two. Are these grandchildren entitled to the obligatory bequest although they are aged thirty-two and above?
All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
A Muslim isn`t obligated to leave a bequest to his grandchildren whose father had passed away; rather, this act is recommended. Therefore, if he left a bequest whereby they get less than one third of the estate then Allah will reward him for that. However, if he left no bequest for them then they get nothing because their paternal uncles are alive and they are closer to the deceased and more entitled to inherit him. This is the position of the four schools of Islamic jurisprudence. However, the Personal Status Law didn`t adopt this position; rather, it gave them the same amount to which their father is entitled when alive but his father or mother are dead; provided that it doesn`t exceed one third of the estate. Therefore, we advise them (Grandchildren) to relinquish this share of the inheritance. If not, then we advise their paternal uncles to overlook the amounts taken from their shares and given to their paternal nephews. And Allah The Almighty Knows Best.
