When to stand up when the Iqamah is being announced?

Q 2: During the Iqamah (call to start the Prayer), do we have to remain seated until the Mu'adhin (caller to Prayer) says the phrase 'the Salah (Prayer) is due to be established' after which we have to stand up for Salah? Is it permissible to say: "May Salah continue to be established for as long as the heaven and the earth continue to exist''?

A: It is permissible to stand up for Salah at the announcement of Iqamah. There is nothing wrong, however, if one remains seated until (Part No. 5; Page No. 67) the Mu'adhin says: "The Salah is due to be established". This is permissible only if the Imam is present at the moment the Iqamah is announced. If, however, the Imam is not present, then one must remain seated until they see him.The Prophet is not reported to have said statements such as 'May Salah continue to be established...' upon the announcement of the Iqamah. Therefore, it is preferable not to utter these words. One may, however, repeat the same words uttered by the Mu'adhin.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
