Hazrat Yazid bin Bishr Suksaki, may Allah have mercy on him, says that when I came to Madinah, I went to the service of Hazrat Abdullah bin Umar, may Allah be pleased with them both. At that time, an Iraqi man came to him and said, "O Abdullah bin Umar, may Allah be pleased with them both! What is the matter that you perform Hajj and Umrah but have stopped striving in the path of Allah (jihad)?" Hazrat Ibn Umar, may Allah be pleased with them both, replied, "May you perish! The foundation of faith is five things: that you worship Allah, establish prayer, pay zakat, perform Hajj, and fast in Ramadan." The man said, "Will you tell me these things again?" Hazrat Abdullah, may Allah be pleased with him, said, "O servant of Allah! Worship Allah, establish prayer, pay zakat, perform Hajj, and fast in Ramadan. The Messenger of Allah, peace and blessings be upon him, told us just like this. After these, jihad is a good deed."
