A:
You should refrain from using these phrases, because they
are a transgression against others by invocations. Allah (Glorified be He) states,
...and transgress not the limits. Truly, Allâh likes not the transgressors.
(Part No. 24; Page No. 263) He (Glorified be He) also states:
...And speak good to people [i.e. Enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم].
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
