It was narrated from Abu Hurairah: “Mention of the martyrs was made in the presence of the Prophet (ﷺ) and he said: ‘The earth does not dry of the blood of the martyr until his two wives rush to him like two wet nurses who lost their young ones in a stretch of barren land, and in the hand of each one of them will be a Hullah* that is better than this world and everything in it.’”
