Narrated Abu Huraira: Allah’s Apostle said, “When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many Rakat he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting {Sahih Bukhari, Volume 2, Book 22, Number 324}

“We created not the heavens, the earth, and all between them, but for just ends. And the Hour is surely coming (when this will be manifest). So overlook (any human faults) with gracious forgiveness. For verily it is thy Lord who is the Master-Creator, knowing all things. And We have bestowed upon thee the Seven oft-repeated verses (Surah al-Fatiha) and the Grand Qur’an. Strain not thine eyes (wistfully) at what We have bestowed on certain classes of them, nor grieve over them: but lower thy wing (in gentleness) to the Believers.”- Al Hijr, 85-88

Indeed, it is We who bring the dead to life and record what they have put forth and what they left behind, and all things We have enumerated in a clear register.
Surah Yā-Sīn (36:12)

Umar ibn al-Khattaab (may Allaah be pleased with him):”If you see that one of you has slipped, correct him, pray for him and do not help Shaytan against him (by insulting him, etc.).”[Tafseer al-Qurtubi, 15/256]

Cause everyone is going to slip, & have there ups and down in their Imaan. But at least they are trying to get back up on their feet and return back to the Deen. Its our job to help each other stay on the right path however, now a days if someone ends up slipping we begin to judge them and forget about them. It should not be like that, instead we should make Dua for one another and help them from not falling too far from the deen, we need to help each other strive for Jannah.!

So who is more unjust than one who fabricated a lie against Allah or denied His signs? Their written fate will reach them; until when Our sent angels come to remove their souls, hence they say to them, “Where are they whom you used to worship besides Allah?” They say, “We have lost them” and they testify against themselves that they were disbelievers. [Surah Aa`raf 7:37]

“If an evil suggestion comes to you from Satan, then seek refuge in Allah . Indeed, He is Hearing and Knowing.”

[Surah Al-A’raf 7:200

Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning.
Surah Al-Mulk(17)

Read in the name of your Lord Who created.

He created man from a clot.
Read and your Lord is Most Honorable,
Who taught (to write) with the pen
Taught man what he knew not.
Nay! verily man is rebellious,
In that he lookes upon himself as self-sufficient.
Surely to your Lord is the return.
Have you seen him who forbids
A servant when he prays?
Have you considered if he were on the right way,
Or enjoined guarding (against evil)?
Have you considered if he gives the lie to the truth and turns (his) back?
Does he not know that Allah does see?
Nay! if he desist not, We would certainly smite his forehead,
A lying, sinful forehead.
Then let him summon his council,
We will call on the angels of punishment (to deal with him)!
Nay, obey him not: But bow down in adoration, and bring thyself the closer (to Allah)!

And those who denied Our signs and were conceited towards them, are the people of hell-fire; they will remain in it forever. [Aa`raf 7:36]

“On the Day of Judgement Allah will give the shade of the Arsh (Throne), to seven, when there will be no shade but the shade of the Arsh….(the last type of person is) a person who praises (remembers) Allah in seclusion and his eyes are then flooded with tears.” [Sahih al-Bukhari]

The Prophet (peace be upon him) said: “The one who repents from a sin is like one who has no sin.” [Ibn Majah]

Al-Hassan al-Basri was once asked, “Shouldn’t we be shy in front of Allah to ask Him to forgive a sin and then we do it again, then we again ask Him to forgive the sin and we do it again?” Al-Hassan answered, ”Satan wishes that he could gain that victory over you. Do not get bored with asking forgiveness.” [Jami al-uloom wal Hikam]

When the Qur’an is recited, listen to it and be silent, so that you may be blessed.
Surah Al-Araf ( 7:204 )

Prophet Muhammad (sallallaahu ’alayhi wa sallam) said, “Du’aa’ is worship.”
(al-Tirmidhi, Hadith 3372)

Al-Hasan Al-Basri (may Allah have mercy upon him) said:

“Almighty Allah has not set a deadline for a believer’s having to do good deeds, except death.”

Then he recited Almighty Allah’s words: And serve thy Lord till the inevitable (death) cometh unto thee (Al-Hijr 15:99)
