The Muffasireen have mentioned that the reply of Prophet Ibrahim (a) was in itself a du’a. There are different stages of itminaan (reliance on Allah). This type of tawkkul is the highest form of itminaan, where a person leaves everything to Allah knowing that whatever is best for him will happen. When Prophet Ibrahim (a) 
landed in the fire, it became a garden, a place of coolness for him. 
Verse 26: When Ibrahim (a) was preaching to his people, Lut (a) 
accepted his message, and believed in him. He was the nephew of Prophet Ibrahim (a). 
Verse 27: There is a difference between Jazaa’ and ‘Ajr. Jazaa’ can be used to refer to both punishment and reward but ‘Ajr only refers to reward. When Prophet Ibrahim (a) was blessed with children, it was a special and divine blessing from Allah (swt). Ishaq was the son of Prophet Ibrahim (a) while Yaqub (a) was his grandson. All the divine books that were revealed to the Prophets were from the lineage of Prophet Ibrahim (a). Perfecting your deeds can only be done in this world but perfecting your knowedge can be done both in this world and in the hereafter. By learning something new, you perfect your knowledge. However, in the Akhirat, there will be things you have never seen and you will witness it. This is how you will learn in the Akhirat-by seeing. 
We pray to Allah (swt) to grant us a better understanding of the Holy Qur’an so that we can implement its teachings in our daily lives. Ameen.
