In the She'b Abi Talib
:
When the Quraysh did that, the Banu Hashim and Banu al-Muttalib gathered round Abu Talib and joined him in his quarters in a narrow valley of Makkah. It was the seventh year of
prophet-hood. However, Abu Lahab ibn Abdul-Muttalib left the Banu Hashim and aligned himself with the Quraysh.
For many months the Banu Hashim lived in misery. The boycott was so rigorously applied and food was so scarce that they had to eat the leaves of trees. Their hungry children's cries could be heard all over the valley. The Quraysh told the merchants not to sell any goods to them. Prices were increased to prevent them from buying even essentials.
They remained in that state for three years. Apart from some kind Qurayshi people who secretly sent food to them they were totally abandoned. The Messenger of Allah was in the same predicament but he continued to call his People to Allah night and day, secretly and openly and the Banu Hashim remained patient.
