Bismillaah Al-Hamdulillaah wa salatu wa salaamu 'ala rasulullaah Amma ba'd
The sincere adviser has a distinguishing sign: when he wishes to enhance the one he is advising, he advises him privately, whereas the sign of the one who wishes to disgrace him is that he advises him in public.
[Rawtadul-Uqalaa of Ibn Hibban (rahimahullaah), p. 196]
Subhanak Allaahuma wa bihamdika ash-hadu anlaa illaaha illa anta astaghfiruka wa atubu ilayk
If I said anything correct, then it is from Allaah (subhanahu wa taa'ala), and if I erred, then that is from me and shaytan.
