I read several hadith that said :  

if you pray at the time of sunrise and sunset, it is like praying between the two horns of shaytaan. These times for salat are prohibited. also it stated that this is the time the Jins pray to shaytaan…. is this a sound hadith?


Praise be to Allaah.
 

Yes, it was narrated in Saheeh al-Bukhaari (581) and
Saheeh Muslim (831) that it is forbidden to pray after Fajr prayer
until the sun has risen above the horizon to the height of a spear, at the
time of noon when the sun is at its zenith, and after the time of ‘Asr until
the sun is fully set. The Prophet (peace and blessings of Allaah be
upon him) told us that the sun rises and sets between the two horns of a
devil, at which time the kuffaar prostrate to it. 


Shaykh Sa’d al-Humayd 

There is nothing in the hadeeth to say that the jinn pray to
the devils at that time, rather the devils (shayaateen) are the evil ones
among the jinn.
