Tariq bin Shihab narrates: A woman from among us intended to perform Hajj and wanted to combine Umrah with her Hajj, so she asked Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). He said: "I find this only in the months of Hajj; Allah, the Mighty and Majestic, says: 'Well-known months' [Surah al-Baqarah: 197]."
