Sahih Muslim | Book 32 | Hadith Number 6367

Narrated by Abu Huraira
Abu Huraira reported that Allah's Messenger (may peace be upon him) said to a woman of the Ansar: In case anyone amongst you sees the sad demise of three children of (hers) and she resigns herself to the will of God hoping to get reward, she would be admitted to Paradise. A woman from amongst them said: Allah's Messenger, even if they (the children who die) are two. Thereupon, he (the Holy Prophet,) said: Even if they are two.
