Here is a list of 10 things that would not take more then 10 minutes of our time. And if we knew what good these actions bring for our happiness in this life and the next, we would spend our life in dedication to these deeds:
10. Pray 2 Rakahs (Salatul Duha) anytime after sunrise and before Dhuhr
Abu Hurayrah - radi Allahu 'anhu - said, "My Khaleel - Allah's Messenger sal Allahu alayhi wa sallam - advised me to do three things (1) That I fast 3 days of each month and (2) To pray 2 rakahs of Duha and (3) That I do my witr before sleeping." - Bukhari and Muslim
9. Pray for Rasul Allah - sal Allahu alayhi wa sallam
He - sal Allahu alayhi wa sallam - said, "Whoever prays for me once, Allah blesses that person 10 times (because of that prayer)." - Muslim
8. Repeat what the Mu'adhdhin is saying
Abdullah ibn Amr narrates: a man said, "O Messenger of Allah, the ones that call the people to prayer receive more reward than us." So Allah's Messenger - sal Allahu alayhi wa sallam - replied, "Say what they say, then when you finish pray for anything and you shall be given it." - Abu Dawood
7. Say 'Subhan Allah - How far Allah is from imperfection!' 100 times
Mus'ab ibn Sa'd said: My father told me that he was with Allah's Messenger - sal Allahu alayhi wa sallam - when he remarked, "Does any one of you not have the ability to attain 1000 good deeds (hasanaat) every day? Let him do tasbeeh (Subhan Allah!) 100 times, it will be written for him 1000 hasanat or 1000 sins will be wiped from his record." - Muslim
6. Play with your children for the sake of Allah
Jabir narrates: We were with Allah's Messenger - sal Allahu alayhi wa sallam - invited for a meal when we passed al-Husayn playing in the alley with some Ansar children. Allah's Messenger - sal Allahu alayhi wa sallam - walked a little faster to go and play with him. He stuck out his hand to take him, but Al-Husayn ran here and there squealing gleefully until Allah's Messenger caught him. Then he - sal Allahu alayhi wa sallam - held his chin with one hand and his head with the other and kissed Al-Husayn and hugged him. - A sound hadith narrated by Bukhari in al adab al mufrad
5. Make Dua' often during times of ease
Rasul Allah - sal Allahu alayhi wa sallam - said, "Whoever it pleases that Allah answers his supplications during times of calamity and hardship, let him increase his supplication amidst the times of ease." - narrated by Tirmidhi and Al Hakim who classified it as authentic.
Bonus: Say the Dhikr after Making Wudu.
RasulAllah sal Allahu alayhi wa sallam said, "If anyone of you, after perfecting his wudu, says, 'Ash hadu an laa ilaaha illAllah, wa ashhadu anna Muhammadan 'Abduhu wa Rasooluh (I bear witness that there is no god but Allah and that Muhammad is his slave and Messenger), the eight gates of Jannah will open for him and he will be permitted to enter from whichever he wishes" (Muslim).
4. Pick up the phone to call your mother (or a close relative) and tell them that you love them.
RasulAllah sal Allahu alayhi wa sallam said, "The Wasil (One who fulfils the rights of his ties of kinship) is not the one who does good when family members do good (and bad when they are bad). The Wasil is the one who, when family members cut him off he does good to them" (Interpretation of a Bukhari).
3. Take a few minutes to stop and contemplate Allah's amazing creation, of your eyes, voice, and entire body. Allah says in the Qur'an:
And on the earth are signs for the certain (in faith) /And in yourselves, will you not see (and contemplate) (Az-Zariyat 51/20-21)?
2. Share a part of your lunch with someone.
RasulAllah sal Allahu alayhi wa sallam said, "Oh Abu Dharr! If you cook any soup, increase its water and then look to your neighbors and give them some of it" (Muslim).
And the number one deed you can do in less then 10 minutes...
1. Make du'a for your brother in his absence.
RasulAllah sal Allahu alayhi wa sallam said, “If a person prays for his (or her) brother in their absence (without them knowing), an angel (hears the du'a) and replies, ‘Ameen! And may Allah give you the same’”(Ahmad, Abu Dawood and Tirmidhi).
In fact, whenever the Sahaabah and Taabi'een wanted their du'a to be answered quickly, they would ask the same thing for their brother in order to get the angel to reply, ‘Ameen! And may Allah give you the same.’
In sha Allah, let's all try at the very least to find one deed from this list and implement it in this coming week. After it has become habit, try another deed and so on.
