Allah is capable of healing all wounds

And the heart of Moses’ mother became empty [of all else]. She was about to disclose [the matter concerning] him, had We not bound fast her heart that she would be of the believers. (Qur’an 28:10)
The Pharaoh at the time of Musa was a tyrant who exploited the people of Israel, he also killed their newborn “male” babies. The reason behind this evil practice was the belief of the Israelites that there would come a child from the lineage of Ibraheem (AS) (Abraham),who would destroy the kingdom of Pharaoh. When Musa (AS) was an infant, Allah revealed to his mother to put him in a basket and cast him in the river, to protect him from Pharaoh’s guards. How hard is it for a mother to let go of her child and put him in the water with her own bare hands?! Can you imagine how she must have felt? She has done the inconceivable! Her faith in Allah was stronger than her motherly instincts! Allah mentions in this Ayah that the heart of the mother of Musa (AS) became “empty”. She became emotionally paralysed from this traumatic event    She was almost going to give up her secret that Musa (AS) is indeed her child! She was almost going to call out that this is her child and follow him to the Pharaoh’s castle, where the basket landed, and take him back! But Allah strengthened her heart and calmed her down. Allah is the only one capable of making you overcome tragedy If you return to him and ask for his help. He is the one that can give you the emotional capacity to overcome hardship  

If you ever feel unable to move on from a certain calamity that has befallen you,

Ask Allah to strengthen your heart like he did with the mother of Musa (AS)!
