Assalamu alaikum. I wanted to perform itikaf for the last 3 days of Ramadan. What time should I sit? Please reply as soon as possible.
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
If a person intends to do i'tikaf for 3 days and nights in Ramadan, he/she should sit i'tikaf before maghrib enters on the 1st day. And he/she can exit from i'tikaf after maghrib of 3rd day.
For e.g: If he starts i'tikaf on Monday before maghrib prayer which is his 1st day. Then his 3rd day will be on Thursday after maghrib. Now he can exit his i'tikaf.
Only Allah knows best
