Adding the phrase: 'Prayer is better than sleep' for the Fajr Adhan

Q: In the call to Fajr Prayer, the Mu'adhin (caller to Prayer) says 'Assalatu khayrun mina-nawm [Prayer is better than sleep]'. If I were performing Salah alone not in congregation should I say, 'Assalatu khayrun mina-nawm' when calling Adhan (call to Prayer), or not?

(Part No. 6; Page No. 62)  A: Yes, you should say it, because there is no difference between calling Adhan while praying individually or in congregation, and it is part of the wordings of the correct Adhan in the Fajr (Dawn) Prayer.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
