Some Rulings of Iddah

Summarized Fatawaa

Which is more excellent for a woman: to pray in the mosque or in her house?

Praise be to Allah, and peace and blessings be upon our Master, the Messenger of Allah.
 
Our Master the Prophet ﷺ said: 'It is more excellent for a woman to pray in her house than in her courtyard, and more excellent for her to pray in her private chamber than in her house.' Therefore, a woman’s adherence to her home and her refraining from going to the mosques—in obedience to the command of Allah the Exalted—attains a great reward and abundant recompense. Furthermore, women praying in congregation within their homes is better than their attendance at the mosques, based on the aforementioned Hadith. And Allah the Exalted knows best.

Does the clipping of nails nullify ablution?

No, it does not, and it is preferable to wash the hands afterwards.

What is the ruling on someone who prays but does not fast, without a valid excuse?

Fasting is one of the pillars of Islam, and a Muslim's faith is incomplete if they neglect the obligation of fasting while being physically capable of observing it.

What is the ruling on someone who fasts but does not pray?

A Muslim must be diligent in fulfilling all obligations, and after the Shahadah, prayer is the most important duty.
● If someone abandons prayer out of disregard, they are considered a disbeliever, and their fasting is not accepted.
● If they abandon prayer out of laziness, they are still a Muslim, and their fasting remains valid, but they have committed a grave sin by neglecting prayer.
