We gave the oath of allegiance to Allah's Messenger (ﷺ) that we would listen to and obey him both at the time when we were active and at the time when we were tired and that we would not fight against the ruler or disobey him, and would stand firm for the truth or say the truth wherever we might be, and in the Way of Allah we would not be afraid of the blame of the blamers. (See Hadith No. 178 and 320)

The Prophet (ﷺ) went out on a cold morning while the Muhajirin (emigrants) and the Ansar were digging the trench. The Prophet (ﷺ) then said, "O Allah! The real goodness is the goodness of the Here after, so please forgive the Ansar and the Muhajirin." They replied, "We are those who have given the Pledge of allegiance to Muhammad for to observe Jihad as long as we remain alive."

Whenever we gave the Pledge of allegiance to Allah's Messenger (ﷺ) for to listen to and obey, he used to say to us, for as much as you can."

I witnessed Ibn `Umar when the people gathered around `Abdul Malik. Ibn `Umar wrote: I gave the Pledge of allegiance that I will listen to and obey Allah's Slave, `Abdul Malik, Chief of the believers according to Allah's Laws and the Traditions of His Apostle as much as I can; and my sons too, give the same pledge.'

I gave the Pledge of allegiance to the Prophet (ﷺ) that I would listen and obey, and he told me to add: 'As much as I can, and will give good advice to every Muslim.'

When the people took the oath of allegiance to `Abdul Malik, `Abdullah bin `Umar wrote to him: "To Allah's Slave, `Abdul Malik, Chief of the believers, I give the Pledge of allegiance that I will listen to and obey Allah's Slave, `Abdul Malik, Chief of the believers, according to Allah's Laws and the Traditions of His Apostle in whatever is within my ability; and my sons too, give the same pledge."
