What is the ruling for missing obligatory prayers for some time in life without a valid excuse? Is it an obligation to make up the missed obligatory prayers whenever the person realizes that he had committed a sin by neglecting them on purpose?
Establishing prayers or (Iqamat al-Salat) is the second most important pillar of Islam after declaring faith in God and His Messenger (peace and blessings be upon him).
God the Almighty says, "Establish obligatory prayers. Verily, such prayers are enjoined on the believers at stated times" (Quran 4:103).
The five daily prayers form the most important ritual of worship in a Muslim’s life. The Prophet (peace and blessings be upon him) said: “Prayer is a pillar of the religion (Islam). Whoever establishes it, establishes religion; and whoever destroys it (i.e. neglects it), destroys religion” (Baihaqi).
