It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The five obligatory prayers and from one Friday to the next Friday are an expiation for the sins committed in between, as long as major sins are not committed."

Sayyiduna Abu Hurairah (may Allah be pleased with him) and Abu Sa'id Khudri (may Allah be pleased with him) narrate from the Prophet (peace and blessings be upon him) that he ascended the pulpit and then said: "By the One in Whose hand is my soul." He said this three times. Then he (peace and blessings be upon him) fell silent, and each one of us lowered his head and began to weep out of grief due to the oath of the Messenger of Allah (peace and blessings be upon him). Then he (peace and blessings be upon him) said: "Whoever performs the five obligatory prayers, fasts in the blessed month of Ramadan, and avoids the seven major sins, for him the gates of Paradise will be opened on the Day of Resurrection until those gates (out of joy) will be shaking." Then the Prophet (peace and blessings be upon him) recited this verse: «‏‏‏‏إِن تَجْتَنِبُوا كَبَائِرَ مَا تُنْهَوْنَ عَنْهُ نُكَفِّرْ عَنكُمْ سَيِّئَاتِكُمْ» ‏‏‏‏ [ سورة النساء ] "If you avoid the major sins which you are forbidden, We will remove from you your lesser sins."
