"So whoever does an atom's weight of good will see it, And whoever does an atom's weight of evil will see it."-Quran 99:7-99:8

What does Islam say about beating wife, sister or any female

Peace

The Messenger of Allah, peace and blessings be upon him, said "By him in whose hand my soul is! You will not enter paradise until you believe and you will not believe until you love each other. May I inform you of something, if you do, you love each other? Spread greeting amongst you"

Smiling and greeting others (if you know them or not) is sunnah.

Keep smiling and keep spreading the love! :)

Mercy for the animals

Prophet Muhammad (peace be upon him) was the embodiment of mercy, he showed compassion to all those aroud him, family, orphans, friends, strangers and even enemies. He also treated the environment and animals with respect and mercy. He taught his followers that animals were part of God´s creation and they should be treated with dignity and due care.
Allah says in the Quran "And we have sent you O Muhammad not but as a mercy for all of humankind, jinn, and all that exists". (Quran 21:107.)

Prophet Muhammed (pbuh) said:
Feed others, and greet those whom you know and those whom you do not know.

Indeed, your Lord is Allah , who created the heavens and earth in six days and then established Himself above the Throne. He covers the night with the day, [another night] chasing it rapidly; and [He created] the sun, the moon, and the stars, subjected by His command. Unquestionably, His is the creation and the command; blessed is Allah , Lord of the worlds.(Quran 7:54)

The seven heavens and the earth and all that is therein, glorify Him and there is not a thing but glorifies Him praise. But you understand not their glorification. Truly, He is ever forbearing, and oft-forgiving. (Quran 17:44)

[And] who created seven heavens in layers. You do not see in the creation of the Most Merciful any inconsistency. So return [your] vision [to the sky]; do you see any breaks? Then return [your] vision twice again. [Your] vision will return to you humbled while it is fatigued.
(Quran 67:3-4). 

10 things that bring the love of Allah -Ibn Qayyim (May Allah have mercy on him)

1) Recitation of the Quran with reflection and with understanding of its meanings.

2) Seeking closeness to Allah by performing voluntary deeds after having performed obligatory ones, for that leads one to the highest levels of love.

3) Remembering Allah during every situation - with one´s time, heart, and deeds, one´s share of that love is to the degree of one´s share in that remembrance.

4) Preferring what He loves to what you love when your desires are strong.

5) Allowing your heart to reflect on His name and attributes.

6) Reflecting on His many favors and blessings, both the apparent ones and the hidden ones, for that leads to His love.

7) Having your heart softened as it is worshipping Allah.

8)Being alone with Him in worship when He descends during the last third of the night. And this means to invokeHim, to recite His speech, to stand with all sincerily and with good manners and with good submission, and then to end that with repentance and with seeking His forgiveness.

9) Sitting with those who are truthful in their love of Allah.

10) Staying away from all that creates barriers between the heart and Allah.
