Bismillah
Oh no I was not offended brother Waheed, I was just clearing tha fact that I was a sister that is all, :D
And we did not say that you are here to make a massive debate, you are here just to understand the truth about Dhikr according to Quran and Sunnah :) and we are trying our best to help you, so take it easy and do not hesitate to ask anything you want to be cleared up. Now at the time of Prophet Salla Allah alayhee wa salam there were no lights to put on and off, there was oil to light in small lanterns, and sometimes they will not find oil to light it up, so that has nothing to do with must put light off or on.
Yes he used to pray at night for hours, he used to recite Albaqara Al-Imran and Al-Nisa in one rakaa, but he is the Prophet Sala Allah alayhee wa salam, even his companions found it hard to do what he used to do, so how can we now at this time and all this rapid life do the same. You are not obliged to do it, just 2 or 4 raka's followed by shafe'and witer will do, and then some Athkar which is Dua' and you have the ones i provided for you is more than enough dear brother.
And since you are from Pakistan now I understand what your family is doing, and what they do is not from Islam at all, I have seen some of these rituals on TV, and for sure they are Bida' brother, all Scholars following Quran and Sunna say it is haram, I will make more research about this to give you more proof inshaAllah than just my word as seeing and hearing, B) so hold on there I will be back soon with more proof inshaAllah.
Salam
