“So (O Messenger), endure what they say and proclaim the purity and praise of your Lord before the sun rises and before it sets. And in some hours of night proclaim His purity, as well as at the edges of the day, so that you may be
pleased." TaHa (20:130)
Ibne Umar RadiyAllahu `anhu narrates that Rasulullah Sallallahu `alaihi wasallam said: “Islam has been built upon five pillars – Bearing witness that ‘None is worthy of worship but Allah and that Muhammad Sallallahu `alaihi wasallam is Messenger of Allah,’ and to establish Salah and give Zakah, and perform Hajj, and Saum (fasting) of Ramadan.”
Abu Hurairah RadiyAllahu `anhu narrates that Rasulullah Sallallahu `alaihi wasallam used to say: “The five Salah; and the (prayer of) Jumu’ah (Friday) from the last Jumu,ah; and fasting (of Ramadan) from the last Ramadan; are atonements for (the sins) that had been committed between them, provided the sinner avoids the major sins”.
