Be careful from hurting animals !!! Be nice to them ..

Abu Hurayra narrates: The Messenger of Allah (pbuh) said,

"A man felt very thirsty while he was on the way; he came across a well. He went down the well, quenched his thirst and came out. Meanwhile he saw a dog panting and licking mud because of excessive thirst. He said to himself, "This dog is suffering from thirst as I did." So, he went down the well again and filled his shoe with water and watered it. Allah was pleased with him for that deed and forgave him."

The people with the Messenger of Allah (pbuh) said,

"O Messenger of Allah! Is there a reward for us in serving the animals?" The Prophet (pbuh) said,

"Yes, there is a reward for serving any animate (living being)."

Ibn Umar narrates. The Messenger of Allah (pbuh) said,

"A woman went to Hell due to imprisoning a cat in the house. She did not give it any food and did not let it go out and eat the insects on earth." [Bukhari, Bad'ul-Khalq 17, Shirb 9, Anbiya 50; Muslim, Birr 151, (2242)]
