Repentance for neglecting prayer

Remember how Allaah has blessed you by bringing
you back to Islam after you have been neglecting salaah, and keep on doing the
prayers at the right times. Do more naafil (supererogatory or extra) prayers
to make up for the fard (obligatory) prayers that you have missed, as was advised
in the saheeh hadeeth narrated by Hurayth ibn Qubaysah, who said: I came
to Madeenah and prayed, O Allaah, send me a righteous companion.
I went and sat with Abu Hurayrah and said: I asked Allaah to bless me
with a righteous companion; tell me a hadeeth that you heard from the Messenger
of Allaah (peace and blessings of Allaah be upon
him), so that I may benefit therefrom. He said: I heard the Messenger
of Allaah (peace and blessings of Allaah be upon
him) say that the first thing for which a person will be brought to account
on the Day of Resurrection will be his prayer. If it is sound, he will be successful,
and if it is lacking in any way, he will be doomed. If his obligatory prayers
are lacking, the Lord will say: Look and see whether My slave has any
voluntary prayers which may be used to make up what is lacking in his obligatory
prayers. Then all his deeds will be examined and dealt with in the same
way. (Reported by al-Tirmidhi, no. 413; see
also Saheeh al-Jaami, 2020).
Abu Dawood reported from Anas ibn Hakeem al-Dabbi that he came to Madeenah and
met Abu Hurayrah. He said: He asked me about my lineage so I told him
about it, then he said: O young man, shall I not tell you a hadeeth?
I said, Of course, may Allaah have mercy on you, and I think he
mentioned it from the Prophet (peace and blessings
of Allaah be upon him). He said: The first thing that people will be asked
about on the Day of Resurrection will be their prayers. Our Lord will say to
His angels (although He knows best): Look at My slaves prayers:
are they complete or is something lacking? If they are complete, they
will be recorded as such, but if something is lacking, He will say: Look
and see if My slave has any voluntary prayers to his credit. If this proves
to be the case, He will say: Make up his (missing) obligatory prayers
with his voluntary prayers. Then the rest of his deeds will be dealt with
in the same manner. (Saheeh al-Jaami, 2571)
