Is it true that Frogs are considered to be sacred or pious creatures in Islam?
When i made the search in the internet, i bumped into the following discussion in Islamweb: :
"It is confirmed in a Hadeeth that it is prohibited to kill frogs, and the jurists 
relied on this evidence in prohibiting eating them. Some of them said that the reason is that they are dirty as stated by Al-Munaawi 
. Moreover, it is confirmed that ‘Abdullaah Ibn ‘Amr 
said that the reason for this is that its croak is Tasbeeh (saying Subhaanah Allaah, i.e. how perfect Allaah is) and Al-Bayhaqi classified this narration from Ibn ‘Amr as Saheeh [authentic].

Besides, Ash-Shawkaani
said that Ibn ‘Amr used to take from the Israelites. It was also reported from Anas that the frog took water in its mouth to put out the fire that was prepared to burn the Prophet Ibraaheem (Abraham) 
.As regards the wording of its Tasbeeh, then we are not aware of any authentic evidence of it. However, it was reported from Anas
that it says: “Subhaanaka
wa bihamdika muntaha ‘ilmika” (How perfect You are O Allaah, and I
praise You to the farthest boundary of Your Knowledge.” Whereas, Az-Zamakhshari said that it says “Subhaanah Al-Malik Al-Qudoos” (How perfect The King, The Holy One is.) What is mentioned about the frogs making Tasbeeh – if this is confirmed – is evidence of its excellence as it is said that its croak is Tasbeeh. However, even if this is not confirmed, they are still included in the general creatures that make Tasbeeh, as Allaah Says (what means): {The seven heavens and the earth and whatever is in them exalt Him. And there is not a thing except that it exalts [Allaah] by His praise, but you do not understand their [way of] exalting.}[Quran 17:44]
