We feared that stones would fall from the sky
Due to the martyrdom of Imam Hussain (May Allah be well pleased with him), the people of Madina became strongly opposed to Yazid and pledged their allegiance to Hadhrat ‘Abdullah bin Hanzlah (May Allah be well pleased with him). Yazid sent an army to attack Madina, which attacked the people of Madina and persecuted its citizens. On that occasion, Hadhrat ‘Abdullah bin Hanzlah (May Allah be well pleased with him) spoke to the people of Makkah and described the unislamic activities of Yazid. Hadhrat Muhammad bin Sa’ad (May Allah be well pleased with him) who is a Hadith-expert as well as a historian, has written in Tabaqaat e Kubra, Vol. 5 Pg No. 66.
Translation: The people of Madina agreed to pledge their allegiance to Hadhrat ‘Abdullah bin Hanzlah (May Allah be well pleased with him) and gave him authority over their affairs. He took the pledge from them to fight till their last breath. Then he said: O my community! Fear Allah, who has no equal. By Allah! We stood up against Yazid, when we feared that stones would be rained on us from the sky. He is such a person, who declares marriage with mothers, daughters and sisters as permissible, who drinks wine and abandons Salaat. By Allah! If no one from the people supported me, even then I will use my courage and bravery in this matter for the sake of Allah. (Tarikh Ul Khulafa, Pg No. 167, As Sawaaiq Al Muhriqa, Pg No. 132)
