Be Kind to Animals
Kindness is not given to one type of species alone. If you have a kind heart, it must have the compassion, love and care for each and every creation made by Allah SWT. If you can be kind to people, you also have to be kind to what surrounds you.
Although most of our environments doesn't show emotions towards us, we should always remind ourselves that they are created because they also have purpose, just like us.
Prophet Muhammad SAW has cautioned us to be kind and merciful towards all living creatures.
“God has ordained kindness (and excellence) in everything. If the killing (of animals) is to be done, do it in the best manner, and when you slaughter, do it in the best manner by first sharpening the knife, and putting the animal at ease.”
"When you set your dog (for the chase), mention the name of God if he catches the game, and you reach it while it is still alive, cut, its throat quickly (so it won’t suffer).”
The Prophet SAW also said, “Whoever kills a sparrow or anything bigger than that without a just cause, God will hold him accountable on the Day of Judgment.” The listeners asked, “O Messenger of God, what is a just cause?” He replied, “That he will kill it to eat, not simply to chop off its head and then throw it away.”
One of Prophet Muhammad’s companions narrates, “We were on a journey and during the Prophet’s absence, we saw a bird with its two chicks; we took them. The mother bird was circling above us in the air, beating its wings in grief. When Prophet Muhammad returned he said, “Who has hurt the feelings of this bird by taking its chicks? Return them to her.”
When Prophet Muhammad and his companions migrated to Medina, they noticed that people cut off camels’ humps and the fat tails of sheep for food. The Prophet forbade them from them from doing this and said, “Whatever is cut off an animal while it is still alive, is carrion and is unlawful to eat.”
If one has no purpose for killing an animal, he should refrain for doing so. After all, how can you be a kind person when you are round and about killing and hurting other living creatures?
Another point to take is that instead of throwing away your leftovers, please feed it to the animals in your neighborhood. Don't be stingy with food. They are blessings from the Almighty and instead of giving out the food that you won't eat, you throw it away. There is no logic with that.
Give love even to those that can't respond back as how humans would.
