Saeed Ibn al Musayyib would say, the one who prays Maghrib and Esha in jamaat has caught Laylatul Qadr! So, strive to pray them in jamaat!
Praying at least Fajr and Esha in the musjid
Doing morning and afternoon adkhar
Adkhar before sleep
Memorise the book of Allah
Constantly doing dhikr; including lots of istighfar
Portion of the night prayer whether before or after sleep
Praying Sunnah prayers
These are just some of the ibaadaat a person should be doing. These are basic actions that even a pious Muslim should be doing.
Abdullah Ibn Umar (ra) would say, if we didn’t see someone in the Musjid for esha and fajr we would think he’s from the hypocrites.
Unless he oversleeps or lives far and so on of course.
If your seeking of knowledge is not coupled with spirituality then you will become arrogant by the day.
Never forget to do your athkar before sleeping. Remember that esha in jamaat is a sign a person isn’t a hypocrite and the reward being praying half the night! Don’t miss out.
