It was narrated that Sa’ bin Muawiyah said: “I met Abu Dharr and said: ‘Tell me a Hadith.’ He said: the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: There are no two Muslims, three of whose children die before reaching puberty, but Allah will forgive them by virtue of His mercy towards them.” (Sahih)
