The Prophet ﷺ said that Umrah to Umrah is an expiation for what is between them, and an accepted Hajj has no reward but Paradise. Allah says: complete the Hajj and the Umrah for Allah (2:196). It can be done at any time of the year.
1The steps
Ihram from the miqat with the intention for Umrah, and the talbiyah.
Tawaf of the Kaaba seven times, starting and ending at the Black Stone, then pray two rak'ahs behind the Station of Ibrahim if possible.
Sa'i, seven laps between Safa and Marwa, starting at Safa and ending at Marwa.
Shaving or shortening the hair (for women, a fingertip's length from the ends).
2Women and Umrah
A woman performs Umrah as men do. She wears her ordinary modest clothes, and in ihram she does not wear a face veil (niqab) or gloves, as reported in the hadith, although she covers from men who are not her mahram in other ways.
Where the schools differ
The four Sunni schools agree on the main ruling above and differ in these points. No school is preferred here.
The ruling. the Hanafi and Maliki schools say Umrah is a sunnah (stressed); the Shafi'i and Hanbali schools say it is an obligation once in life, like Hajj.
Kuma ku cika hajji da umra dõmin Allah. To idan an kange ku, to, ku bãyar da abin da ya sauƙaƙa na hadaya. Kuma kada ku aske kãnunku, sai hadaya ta kai wurinta. To, wanda ya kasance majinyaci daga cikinku, kõ kuwa akwai wata cũta daga kansa (ya yi aski) sai fansa (fidiya) daga azumi ko kuwa sadaka ko kuwa yanka.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " الْعُمْرَةُ إِلَى الْعُمْرَةِ كَفَّارَةٌ لِمَا بَيْنَهُمَا، وَالْحَجُّ الْمَبْرُورُ لَيْسَ لَهُ جَزَاءٌ إِلاَّ الْجَنَّةُ ".
