Rulings on the New-Born

Summarized Fatawaa

Is it permissible for the person who hasn`t made wudu` (state of minor ritual impurity) to perform the Adhan?

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
 
It is disliked (Makruh) for a person in a state of minor ritual impurity (Hadath Asghar) to perform the Adhan. However, if he does so, his Adhan is considered valid and fulfills the sunnah of the Adhan despite it being disliked. And Allah the Exalted knows best.

What is the ruling on using a miswak (tooth-stick) during the day in Ramadan?

It is permissible to use a miswak before noon while fasting. However, according to the Shafi'i school, it is disliked (makruh) after noon in order to preserve the natural effect of fasting in the mouth, as the Prophetﷺ said in authentic hadith:
"The breath of a fasting person is more pleasant to Allah than the fragrance of musk."

What is the ruling on istinja' after urination, and is it done with water and soap or with water only?

Istinja' from urine and stool is obligatory. It is permissible to perform istinja' with water alone, or with toilet paper alone. The best way is with toilet paper then water. If one wishes to suffice with one of them, then water is better. And Allah the Almighty knows best.

What is the ruling on performing the obligatory prayer immediately after the commencement of the Adhan?

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
 
It is permissible to perform the obligatory prayer (Fard) immediately after the commencement of the prayer time. As the Adhan (call to prayer) serves as a sign that the time has entered, it is permissible to pray as soon as the Adhan begins. However, it is recommended (Mustahabb) for whoever hears the Mu’adhin to repeat what he says. If the Adhan occurs while one is already engaged in prayer, he should repeat the words of the Mu’adhin after he has completed his prayer. And Allah the Exalted knows best.
