وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَا تَأْتِينَا ٱلسَّاعَةُ ۖ قُلْ بَلَىٰ وَرَبِّى لَتَأْتِيَنَّكُمْ عَٰلِمِ ٱلْغَيْبِ ۖ لَا يَعْزُبُ عَنْهُ مِثْقَالُ ذَرَّةٍۢ فِى ٱلسَّمَٰوَٰتِ وَلَا فِى ٱلْأَرْضِ وَلَآ أَصْغَرُ مِن ذَٰلِكَ وَلَآ أَكْبَرُ إِلَّا فِى كِتَٰبٍۢ مُّبِينٍۢ
Those who disbelieve say: The Hour will never come unto us. Say: Nay, by my Lord, but it is coming unto you surely. (He is) the Knower of the Unseen. Not an atom's weight, or less than that or greater, escapeth Him in the heavens or in the earth, but it is in a clear Record,
Surah Saba(34:3)

Fasting
Chapter: Sexual intercourse with wife in Ramadan.
Narrated `Aisha:
A man came to the Prophet (ﷺ) and said that he had been burnt (ruined). The Prophet (ﷺ) asked him what was the matter. He replied, "I had sexual intercourse with my wife in Ramadan (while I was fasting)." Then a basket full of dates was brought to the Prophet (ﷺ) and he asked, "Where is the burnt (ruined) man?" He replied, "I am present." The Prophet (ﷺ) told him to give that basket in charity (as expiation).
