Are "Al-Mugheeth" (The Helper/Provider of Aid) and "Al-Ghiyath" (The Aid/Succour) among Allah's Most Beautiful Names, and is "Al-Jawwad" (The Generous) with a shaddah on the waw, a name of His, along with the proof for each?

Scholars have differed on whether the names "Al-Mugheeth" (The Helper/Giver of Succour) or "Al-Ghiyath" (The Succour/Aid) are among the beautiful names of Allah. However, a group of scholars considered them to be among His names. Sheikh Al-Islam Ibn Taymiyyah said: "Every accountable person must know that there is absolutely no Ghiyath (succour) nor Mugheeth (giver of succour) except Allah," and he mentioned that the Ummah has agreed upon this. He also stated that Al-Ghiyath is Al-Mugheeth, and its meaning is the one who apprehends His servants in times of hardship and answers them. He cited the supplication for rain (Istisqā’): "O Allah, grant us rain (Aghithnā)." Al-Haleemi and Ibn Al-Qayyim also counted them among Allah's beautiful names.
