Imam al-Sadiq has reported: One day, the Holy Prophet entered Fatimah’s house and found her wearing a coarse dress, grinding flour with her own hands, and breastfeeding her son. Seeing this situation, his eyes were full of tears. Turning to her, he said, “O my honorable daughter! Endure the hardships of this world so as to attain the sweetness of the Hereafter.” Fatimah answered, “I praise Allah for His blessings and thank Him for His favor.” At this time, the following verse was revealed:
وَلَسَوْفَ يُعْطِيكَ رَبُّكَ فَتَرْضَى 
And soon will your Lord give you so that you shall be well pleased. (93:5)
