Narrated Nafi: That Ubaidullah bin 'Abdullah and Salim bin 'Abdullah informed him that they told Ibn 'Umar when Ibn Az-Zubair was attacked by the army, saying "There is no harm for you if you did not perform Hajj this year. We are afraid that you may be prevented from reaching the K’aaba." Ibn 'Umar said "We set out with Allah's Apostle and the non-believers of Quraish prevented us from reaching the Ka'ba, and so the Prophet slaughtered his Hadi and got his head shaved.

" Ibn 'Umar added, "I make you witnesses that I have made 'Umra obligatory for me. And, Allah willing, I will go and then if the way to Ka'ba is clear, I will perform the Tawaf, but if I am prevented from going to the Ka'ba then I will do the same as the Prophet did while I was in his company." Ibn 'Umar then assumed Ihram for Umra from Dhul-Hulaifa and proceeded for a while and said, "The conditions of 'Umra and Hajj are similar and I make you witnesses that I have made 'Umra and Hajj obligatory for myself." So, he did not finish the Ihram till the day of Nahr (slaughtering) came, and he slaughtered his Hadi. He used to say, "I will not finish the Ihram till I perform the Tawaf, one Tawaf on the day of entering Mecca (i.e. of Safa and Marwa for both 'Umra and Hajj)."

Narrated Ibn 'Abbas:

Allah's Apostle was prevented from performing ('Umra) Therefore, he shaved his head and had sexual relations with his wives and slaughtered his Hadi and performed Umra in the following year.

Narrated Salim:

(Abdullah) bin 'Umar used to say, "Is not (the following of) the tradition of Allah's Apostle sufficient for you? If anyone of you is prevented from performing Hajj, he should perform the Tawaf of the Ka'ba and between As-Safa and Al-Marwa and then finish the Ihram and everything will become legal for him which was illegal for him (during the state of Ihram) and he can perform Hajj in a following year and he should slaughter a Hadi or fast in case he cannot afford the Hadi."

Narrated Al-Miswar:

Allah's Apostle slaughtered (the Hadi) before he had his head shaved and then he ordered his Companions to do the same.

Narrated Nafi:

That Abdullah and Salim said to 'Abdullah bin 'Umar, "(You should not go for Hajj this year)." 'Abdullah bin 'Umar replied, "We set out with the Prophet (to Mecca for performing 'Umra) and e infidels of Quraish prevented us from reaching the Ka'ba. Allah's Apostle slaughtered his Budn (camels for sacrifice) and got his head shaved."

Narrated Nafi:

When Abdullah bin 'Umar set out for Mecca with the intentions performing 'Umrah in the period of afflictions, he said, "If I should be prevented from reaching the Ka'ba, then I would do the same as we did while in the company of Allah's Apostle ." So, he assumed the Ihram for 'Umra since the Prophet had assumed the Ihram for 'Umrah in the year of Al-Hudaibiya. Then 'Abdullah bin 'Umar thought about it and said, "The conditions for both Hajj and Umrah are similar." He then turned towards his companions and said, "The conditions of both Hajj and Umrah are similar and I make you witnesses that I have made the performance of Hajj obligatory for myself along with Umrah." He then performed one Tawaf (between As-Safa and Al-Marwa) for both of them (i.e. Hajj and Umrah) and considered that to be sufficient for him and offered a Hadi.

Narrated 'Abdur-Rahman bin Abu Layla:

Ka'b bin 'Ujra said that Allah's Apostle said to him (Ka'b), "Perhaps your lice have troubled you?" Ka'b replied, "Yes! O Allah's Apostle." Allah's Apostle said, "Have your head shaved and then either fast three days or feed six poor persons or slaughter one sheep as a sacrifice."

Narrated Ka'b bin 'Umra:

Allah's Apostle stood beside me at Al-Hudaibiya and the lice were falling from my head in great number. He asked me, "Have your lice troubled you?" I replied in the affirmative. He ordered me to get my head shaved. Ka'b added, "This Holy Verse:--'And if any of you is ill, or has ailment in his scalp (2.196), etc. was revealed regarding me. "The Prophet then ordered me either to fast three days, or to feed six poor persons with one Faraq (three Sas) (of dates), or to slaughter a sheep, etc (sacrifice) whatever was available.

Narrated 'Abdullah bin Ma'qal:

I sat with Ka'b bin 'Ujra and asked him about the Fidya. He replied, "This revelation was revealed concerning my case especially, but it is also for you in general. I was carried to Allah's Apostle and the lice were falling in great number on my face. The Prophet said, "I have never thought that your ailment (or struggle) has reached to such an extent as I see. Can you afford a sheep?" I replied in the negative. He then said, "Fast for three days, or feed six poor persons each with half a Sa of food." (1 Sa = 3 Kilograms approx.)

Narrated Abdur-Rahman bin Abu Layla:

(Reporting the speech of Ka'b bin Umra) Allah's Apostle saw him (i.e. Ka'b) while the lice were falling on his face. He asked (him), "Have your lice troubled you?" He replied in the affirmative. So, he ordered him to get his head shaved while he was at Al-Hudaibiya. At that time they were not permitted to finish their Ihram, and were still hoping to enter Mecca. So, Allah revealed the verses of Al-Fidya. Allah's Apostle ordered him to feed six poor persons with one Faraq of food or to slaughter one sheep (as a sacrifice) or to fast for three days.

Narrated Abu Huraira:

Allah's Apostle said, "Whoever performs Hajj to this House (Ka'ba) and does not approach his wife for sexual relations nor commits sins (while performing Hajj), he will come out as sinless as a newly-born child. (Just delivered by his mother)."

Narrated Abu Huraira:

The Prophet (peace and blessings of Allah be upon him) said, "Whoever performs Hajj to this Ka'ba and does not approach his wife for sexual relations nor commit sins (while performing Hajj), he will come out as sinless as a new-born child, (just delivered by his mother)."
