‘Umrah in Rajab

The ahaadeeth indicate that the Prophet (peace and blessings of Allaah be upon him) did not do ‘Umrah during Rajab, as it was narrated that Mujaahid said: ‘Urwah ibn al-Zubayr and I entered the mosque, and there was ‘Abd-Allaah ibn ‘Umar sitting near the room of ‘Aa’ishah (may Allaah be pleased with her). He was asked, “How many times did the Messenger of Allaah (peace and blessings of Allaah be upon him) do ‘Umrah?” He said, “Four times, and one of them was in Rajab.” We did not want to argue with him. We could hear ‘Aa’ishah Umm al-Mu’mineen brushing her teeth (i.e., the sound of the miswaak) in her room. ‘Urwah said, “O Mother of the Believers, did you not hear what Abu ‘Abd al-Rahmaan is saying?” She said, “What is he saying?” He said, “He is saying that the Messenger of Allaah (peace and blessings of Allaah be upon him) did ‘Umrah four times, one of them in Rajab.” She said, “May Allaah have mercy on Abu ‘Abd al-Rahmaan, [the Prophet (peace and blessings of Allaah be upon him)] never did ‘Umrah but he witnesses it (i.e., he was present with him), and he never did ‘Umrah during Rajab.” (Agreed upon).
It was reported by Muslim that Ibn ‘Umar heard this and did not say yes or no. Al-Nawawi said: the fact that Ibn ‘Umar remained silent when ‘Aa’ishah denied what he said indicates that he was confused, or had forgotten, or was uncertain. Hence it is an innovated bid’ah to single out Rajab for making ‘Umrah and to believe that doing ‘Umrah in Rajab has a specific virtue. Nothing to that effect has been narrated, besides the fact that the Prophet (peace and blessings of Allaah be upon him) is not reported to have made ‘Umrah during Rajab at all.

Shaykh ‘Ali ibn Ibraaheem al-‘Attaar (d. 724 AH) said:

One of the things that I have heard about the people of Makkah – may Allaah increase it in honour – is that they do ‘Umrah frequently during Rajab. This is something for which I know of no basis, all I know is that it was reported in the hadeeth that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “ ‘Umrah in Ramadaan is equivalent to Hajj.”

Shaykh Muhammad ibn Ibraaheem (may Allaah have mercy on him) said in his Fataawaa:

As for singling out some of the days of Rajab for any kind of good deed, ziyaarah (visiting the House of Allaah, the Ka’bah) or anything else, there is no basis for this, because Imaam Abu Shaamah stated in his book al-Bida’ wa’l-Hawaadith: specifying acts of worship at times that were not specified by sharee’ah is wrong; no time is to be regarded as better than any other except in cases where the sharee’ah gave preference to a certain act of worship at a certain time, or stated that any good deed done at this time is better than good deeds done at other times. Hence the scholars denounced the practice of singling out the month of Rajab for doing ‘Umrah frequently.

But if a person goes for ‘Umrah during Rajab without believing that this has any particular virtue and because it is just a coincidence that it is easier for him to go at this time, then there is nothing wrong with that.
