There is no explicit text from নবী করীম (সাল্লাল্লাহু আলাইহি ওয়া সাল্লাম) specifying a minimum waiting period between two উমরাহs. Scholars have differed on this matter. Some scholars hold that there is no waiting period — a person may finish one উমরাহ, exit to Tan'eem, enter a new ইহরাম, and perform another উমরাহ immediately. Others recommend waiting until the hair grows back sufficiently to be cut again, as cutting the hair is one of the rites of উমরাহ.
Sheikh Ibn Baz stated that there is no prescribed minimum time between two উমরাহs. A person may perform উমরাহ on behalf of different deceased relatives in succession during the same trip. He considered each উমরাহ to be an independent act of worship with its own reward. However, he noted that spending time in other forms of worship — such as তাওয়াফ, সালাত, and কুরআন recitation — may be more beneficial than rushing between repeated উমরাহs.
Sheikh Al-Albani held a different view, stating that repeating উমরাহs in quick succession during the same trip has no basis in the Sunnah. He noted that নবী করীম performed only four উমরাহs in his entire life, each during a separate journey, and never performed multiple উমরাহs in one trip. He মুস্তাহাব following নবী করীম's example by focusing on worship within the Haram rather than exiting repeatedly for additional উমরাহs.
