The prayer on a prayer mat that has images on it?
It is valid, but it is recommended that one not pray on it, nor on one that has patterns; because they distract him. Otherwise, the mat is stepped on, and that does not harm. However, it is better to pray on a plain place—without images or patterns—so that he does not become distracted in his prayer.
Q: Do you mean by patterns the colors: red and yellow?
A: The patterns that may distract him and cause him to think about them, just as the Prophet (peace and blessings be upon him) said in the story of the khamisah (decorated cloak) in which he prayed.
