Rulings on the New-Born

Summarized Fatawaa

How does the person praying  perform the prostration (Sujud)?

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
 
It is an act of Sunnah for the person praying to descend for prostration (Sujud) by placing their knees first, then placing their hands on the ground, and then placing their nose and forehead simultaneously. It is obligatory that the toes of the feet be on the ground, directed towards the Qibla. And Allah the Exalted knows best.

Can an Udhiyah be made up if its time is missed?

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
 
If the sacrificial animal (udhiyah) is a voluntary (nafl) offering and its prescribed time is missed after the three days of Tashriq have ended, then it is not to be made up as a sacrifice; rather, it becomes merely a sheep for meat.
 
However, if it was a vowed (nadhr) sacrifice and its time is missed, then it must still be slaughtered, and the slaughtered animal is to be treated as it would have been during its prescribed lawful time. And Allah Almighty knows best.

What is the ruling on objecting to the Mosque Imam regarding the joining of prayers due to rain?

 
Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
 
It is not permissible for any of the congregants to object to the Imam in the mosque, whether the objection is to demand the joining of prayers or to oppose it; for the general principle is that the Imam possesses the religious knowledge (Al-Ilm al-Shar‘i) that qualifies him to make the decision in this matter. And Allah the Exalted knows best."

Is it permissible for a woman to shake hands with her brother-in-law?

It is forbidden for the woman to shake hands with her brother-in-law because he isn`t a Mahram (unmarriageable) of hers.
