What is the ruling on one who invokes blessings upon the Prophet (peace be upon him) when something pleases him or he is amazed by something, and is it better to say, "What Allah wills, there is no power except with Allah"?

The Sunnah is for a Muslim, when seeing something that pleases him, to say: "Tabarak Allah (Blessed is Allah)" or "Masha'Allah (As Allah wills)." This is supported by the hadith of Sahl ibn Hunaif (may Allah be pleased with him) when 'Amir ibn Rabi'ah saw him, and he was afflicted by the evil eye. The Prophet (peace and blessings be upon him) said: "Why, when you saw something that pleased you, did you not invoke blessings (barrakta)?" It also states: "Whoever sees something that pleases him and says: 'Masha'Allah, la quwwata illa billah (As Allah wills, there is no power except with Allah),' it will not harm him." It has not been established in the Sunnah that it is recommended to send blessings upon the Prophet (peace and blessings be upon him) when seeing something that pleases one. However, there is no harm in doing so, provided one does not believe it to be a Sunnah and does not make it a substitute for what is legislated.
