Its chain of narration is weak, and the saying "It appeared to Allah" is objectionable. What is the meaning of this?

The mentioned Hadith has a weak chain of narration (Isnad) because it contains an unknown narrator and another who had a weak memory. As for the phrase "بدا لله" (bada li-Llah - it appeared to Allah), its meaning is objectionable and unfitting for Allah. The correct phrase is "بدأ الله" (bada'a Allah - Allah originated/began), meaning Allah legislated or ordained.
