وَمِنَ ٱلْأَعْرَابِ مَن يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ وَيَتَّخِذُ مَا يُنفِقُ قُرُبَٰتٍ عِندَ ٱللَّهِ وَصَلَوَٰتِ ٱلرَّسُولِ ۚ أَلَآ إِنَّهَا قُرْبَةٌۭ لَّهُمْ ۚ سَيُدْخِلُهُمُ ٱللَّهُ فِى رَحْمَتِهِۦٓ ۗ إِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ
And of the wandering Arabs there is he who believeth in Allah and the Last Day, and taketh that which he expendeth and also the prayers of the messenger as acceptable offerings in the sight of Allah. Lo! verily it is an acceptable offering for them. Allah will bring them into His mercy. Lo! Allah is Forgiving, Merciful.
Surah At-Tawba(9:99)
Sahih al-Bukhari
`Umrah (Minor pilgrimage)
Chapter: 'Umra after performing Hajj without having a Hady
Narrated `Aisha:
We set out with Allah's Messenger (ﷺ) shortly before the appearance of the new moon of Dhi-l-Hijja 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 Messenger (ﷺ) 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 (ﷺ) sent `Abdur Rahman with me to at-Tan`im. The sub-narrator adds: He (`Abdur-Rahman) 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.
