Qiamullail actually means 'waking up at night' which means waking up to worship Allah SWT.
People who are qiamullail will leave their bed only to pray, recite takbir to glorify Allah SWT, sing praises to purify Him and pray at night.
The practice of Qiamullail Sunat Prayer is not a new thing, rather it is an act of worship that has become flesh and blood or the practice of the apostles, prophets, pious people and pious scholars since time immemorial.
Together, let's bring ourselves closer to ALLAH S.W.T in order to obtain His Mercy and Pleasure.
God willing......
