On the night of Diwali at 1 am many devi devtay do ishnaan in the sarovar at Sri Harmandir Sahib. Only God knows how many bhagats, rishis, munis do tapp that day with greater efforts than other days. Das only knows that he has been told that Sant Gurbachan Singh ji bhindrenwale gave bachan that this day is considered special and that devtay do ishnaan at 1 am  every Diwali.


Those who do kamai of whatever shabad that feels appropriate to get their iccha (desires) pooran (complete), will have that happen so long as they keep full sharda. Do abhyaas of whatever shabad seems appropriate from 8:30 pm to 1:30 am and do ardass for Guru Maharaj to fulilll your icha. If Maharaj does kirpa then you’ll get it....

It's a Brahmanical practice that if you stay awake all night of Diwali, and do Jaap of certain Mantras, then you can please Devi Lakshmi and get immense wealth. Under the influence of Hindus, many Sikhs too chant Mantras all night. In order to stop this, Sant jee and other Gurmukhs made it a practice to preach that if you must stay awake on the Diwali night, then do so while chanting Gurbani and not Vedic Mantras.

Having said that, there is no significance in Gurmat of Rishis and Devtas doing Ishnaan at 1 am or if they don't do Ishnaan at all. It does not concern us what Devtas and Rishis do. For a Sikh, everyday is same as far as doing Bhagti is concerned. All Sikhs have to get up at Amritvela to chant the Gurmat Naam.

Guru Sahib knows better.

There is also a belief that staying up the whole night just before the Prakash Divas of Sahib Sri Guru Nanak Dev Patshah Ji Maharaj brings laaha worth of Amritvela for one whole year.

Waheguru,
Bhai Mehtab Singh Jio, when is Prakash Divas of Sri Guru Nanak Dev Jio, please?

The belief is that if we stay up for all of any Puranmashi then we will get laha for the whole year. THis is a Nanaksari belief which goes against Panthic Maryada which specifically states not to place any faith in the moons, stars etc.
