يُفَتَّحُ أَبْوَابُ السَّمَاءِ بِالرَّحْمَةِ فِي أَرْبَعِ مَوَاضِعَ عِنْدَ نُزُولِ الْمَطَرِ وَ عِنْدَ نَظَرِ الْوَلَدِ فِي وَجْهِ الْوَالِدَيْنِ وَ عِنْدَ فَتْحِ بَابِ الْكَعْبَةِ وَ عِنْدَ النِّكَاح .
The Prophet Muhammad (S):
The gates of heaven are opened with mercy in four occasions: at the time of the rainfall, when a son looks at the faces of his parents [with the look of kindness on his face], when the door of the Ka'ba gets opened, and at the time of someone’s marriage.
