Salaah

Sitting on a chair and performing Salaah

Q: Many persons due to medical reasons decide that they need to use a chair for Salah with Jamat and they do not consult a reputable scholar, thinking that a doctor's certification or a medical note is sufficient justification.

1. Is this rationale correct?

2. What is the status of a person's Salah in Shar'iah if he uses a chair for Salah when in fact he is not entitled to?

3. Exactly when is a person permitted to use a chair for Salah in Jamaat or otherwise?

Performing Fajar Salaah before Azaan

Q: Can a male perform Fajr salaah 10 to 20 minutes before the Fajr Salaah. I work 70 km away from my work place, it takes at least 1 hour in the morning to get to work I have to open up the building and warehouse that accommodates a staff of 250 people. So I have to leave home by at least 5.30am to make in time to open up for the staff members. Please advise can I as a male perform my Fajr salaah 10 to 20 minutes before the Fajr Azaan?
