Surah al-Hijr (The Valley of Stone) 15 : 51

“This surah was revealed in Makkah, after the revelation of Surah 12, Joseph. The time was a very critical one, falling as it did between the ‘year of sorrow’ when the Prophet lost his wife Khadijah and his uncle Abu Talib and the year when the Prophet migrated to Madinah. The surah thus reflects the needs and requirements of this difficult period.” [Ref: Qutb, Fi Dhilal]

“It is clear from its topics and style that the period of its revelation is similar to that of Surah 14: Ibraheem (Abraham) as two things are quite prominent in its background. Firstly, it appears from the repeated warnings in this Surah that despite the fact that the Prophet had been propagating the Message for many years his people in general had not shown any inclination towards its acceptance, nay they had become more and more obdurate and stubborn in their antagonism, enmity and ridicule with the passage of time. Secondly by that time the Prophet had begun to feel a little tired of making strenuous efforts to eradicate disbelief and opposition of his people. That is why God has consoled and comforted him over and over again by way of encouragement..” [Ref: Mawdudi]
