A Hadees is mentioned in Muslim Shareef: Sayyiduna Salman رَضِىَ اللهُ عَـنْهُ narrates that the Holy Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated: ‘Allah (عَزَّوَجَلَّ) created 100 mercies on the day He created the earth and the sky. Every mercy was put on top of one another in between the earth and the sky. Out of them, one mercy descended onto the earth. From this one mercy, a mother shows affection upon her children and wild animals and birds show affection to one another, to the extent that a horse keeps its feet away from its children in case they get hurt. When the Day of Judgement will be established, Allah (عَزَّوَجَلَّ) will join this one mercy with the remaining 99 mercies and will then shower mercy upon His bondsmen on the Day of Judgement through it.’
