Messenger of Allah ﷺ said, "(The performance of) ʿUmra 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."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الْعُمْرَةُ إِلَى الْعُمْرَةِ كَفَّارَةٌ لِمَا بَيْنَهُمَا وَالْحَجُّ الْمَبْرُورُ لَيْسَ لَهُ جَزَاءٌ إِلاَّ الْجَنَّةُ
