Narrated Abu Huraira:
Allah's Apostle said, "(The performance of) 'Umra is an expiation for the sins committed (between it and the previous one). And the reward of Hajj Mabrur (the one accepted by Allah) is nothing except Paradise."
Narrated Aisha:
We set out along with Allah's Apostle shortly before the appearance of the new moon (crescent) of the month of Dhi-l-Hijja and he said to us, "Whoever wants to assume Ihram for Hajj may do so; and whoever wants to assume Ihram for 'Umra may do so. Hadn't I brought the Hadi (animal for sacrificing) (with me), I would have assumed Ihram for 'Umra." ('Aisha added,): So some of us assumed Ihram for 'Umra while the others for Hajj. I was amongst those who assumed Ihram for 'Umra. The day of 'Arafat approached and I was still menstruating. I complained to the Prophet (about that) and he said, "Abandon your 'Umra, undo and comb your hair, and assume Ihram for Hajj;." When it was the night of Hasba, he sent 'Abdur Rahman with me to At-Tan'im and I assumed Ihram for 'Umra (and performed it) in lieu of my missed 'Umra.
Narrated 'Aisha:
We set out with Allah's Apostle shortly before the appearance of the new moon of Dhi-l-Hiija and he said, "Whoever wants to assume Ihram for 'Umra may do so, and whoever wants to assume Ihram for Hajj may do so. Had not I brought the Hadi with me, I would have assumed Ihram for 'Umra." Some of the people assumed Ihram for 'Umra while others for Hajj. I was amongst those who had assumed Ihram for 'Umra. I got my menses before entering Mecca, and was menstruating till the day of 'Arafat. I complained to Allah's Apostle about it, he said, "Abandon your 'Umra, undo and comb your hair, and assume Ihram for Hajj." So, I did that accordingly. When it was the night of Hasba (day of departure from Mina), the Prophet sent 'Abdur Rahman with me to At-Tanim.
The sub-narrator adds: He ('AbdurRahman) let her ride behind him. And she assumed Ihram for 'Umra in lieu of the abandoned one. Aisha completed her Hajj and 'Umra, and no Hadi, Sadaqa (charity), or fasting was obligatory for her.
Narrated 'Aisha:
We set out assuming the Ihram for Hajj in the months of Hajj towards the sacred precincts of Hajj. We dismounted at Sarif and the Prophet said to his companions, "Whoever has not got the Hadi with him and likes to make it as 'Umra, he should do it, but he who has got the Hadi with him should not do it." The Prophet and some of his wealthy companions had the Hadi with them, so they did not finish Ihram after performing the 'Umra. The Prophet came to me while I was weeping. He asked me the reason for it. I replied, "I have heard of what you have said to your companions and I cannot do the 'Umra." He asked me, "What is the matter with you?" I replied, "I am not praying." He said, "There is no harm in it as you are one of the daughters of Adam and the same is written for you as for others. So, you should perform Hajj and I hope that Allah will enable you to perform the 'Umra as well." So, I carried on till we departed from Mina and halted at Al-Mahassab. The Prophet called 'Abdur-Rahman and said, "Go out of the sanctuary with your sister and let her assume Ihram for 'Umra, and after both of you have finished the Tawaf I will be waiting for you at this place." We came back at mid-night and the Prophet asked us, "Have you finished?" I replied in the affirmative. He announced the departure and the people set out for the journey and some of them had performed the Tawaf of the Ka'ba before the morning prayer, and after that the Prophet set out for Medina.
Narrated Abu Huraira:
The Prophet said, "Traveling is a kind of torture as it prevents one from eating, drinking and sleeping properly. So, when one's needs are fulfilled, one should return quickly to one's family."
