i want to ask...i need the answer..who..knows it in authentic way..or hadiths..?

I think you are talking about Qazaa (performing those Salaah that you missed) but you don't know how many you missed.

Right, first of all there are two ways of doing Qazaa :

1. For example you missed 100 Salaahs so you can start from 100 and work your way down to 1, in simple words start doing Qazaa from the last Salaah you missed until you reach the first Salaah that you missed thus completing your Qazaa.

2. This is the opposite of the first way, which is to start from 1 (the first Salaah you ever missed) and working your way up to 100 (the last Salaah that you missed).

But the problem is you don't remember how many you missed, the solution to this is the amount of Salaah that you know for definite you missed do Qazaa more than that, for example you know for definite that you missed 50 Salaahs so perform more, perform 60 Salaahs, this way your doubt will disappear.

Last thing, the only difference in Qazaa is the intention, you have to make intention that you are performing Qazaa.

I hope that helped.

As far as I know if you miss any of your salah you should pray them when you remember or when you are next able to.

u can pray them later but u have to say that you're intention is to pray them. when you forget to pray, you can only do the prayers that you forgot in the same day later. make sure you dont pray during the sunrise or sunset. oh, and u have to do them on time if you can. u cant purposefully skip.

Salam and khair inshAllah

A muslim that knows how to pray and doesn't pray correctly is not going to be better than one that knows not how to pray and as intention to do so.

The Prophet (peace and blessings be upon him) said, “Whoever oversleeps and misses his prayer or forgets to do it, let him pray as soon as he remembers it.”

if u think u prayed 3 or for, count as 3 [the lesser amount, then, do sujuud al-sahoo
