Ayesha mounting on a camel took command of the army, and it set off on the march to Basra. The prominent women of Makkah traveled with Ayesha for some distance outside Makkah to see her off. These included Hafsa, another wife of the Holy Prophet. Hafsa intended to accompany Ayesha to Basra, but her brother Abdullah b Umar persuaded her to return to Makkah, as in the war between the two parties of the Muslims it was expedient to remain neutral. As the women took leave of Ayesha, they wept bitterly because of the uncertainty of fortune that lay in store for the army of Makkah. Here a dead camel was sighted from which blood flew profusely. This was taken to be a bad omen indicating that as a result of the campaign they were undertaking much blood was likely to flow. According to the Arab chronicles the day of the departure of the army of the confederates for Basra came to be known as the "Day of Tears", on account of the heavy tears shed at the time of the departure of the troops.
"When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him."
Prophet Mohammed (PBUH)
"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
Sunan Ibn Mājah
"Every day two angels come down from Heaven and one of them says, 'O Allah! Compensate every person who spends in Your Cause,' and the other (angel) says, 'O Allah! Destroy every miser.'"
