Praise be to Allah.
1 – You can serve Islam by having a correct resolve and sincere intention, for Allaah blesses an action that is done sincerely for His sake alone, even if it is little. Sincere devotion, if it becomes a constant feature of acts of worship and obedience, even if they are small or simple in the sight of the one who does them, makes them great in the sight of Allaah, so Allaah will forgive him for major sins because of that, as it says in the hadeeth about the piece of paper on which is written La ilaaha ill-Allaah.
2 – You can serve Islam by knowing the right way and following it. The Straight Path means following the way of our Prophet Muhammad (peace and blessings of Allaah be upon him) with regard to the principles, ways and means of da’wah and being patient in adhering to that, whilst treating people with kindness and compassion, because they are suffering from the disease of sin.
3 – You can serve Islam by making the most of all available means and circumstances. This is a great blessing, for all means are permissible except those which have been forbidden by Allaah. So we call people to Allaah by all means prescribed in sharee’ah, whilst paying attention to the evidence of sharee’ah and correct etiquette.
4 – You can serve Islam by giving precedence to that which is in the interests of Islam over your own whims and desires. Serving this religion means giving what is most precious of your money, effort, time, thought, etc. Have you not seen those who love sport (football or soccer) for example, how they devote their efforts, time and money to their beloved sport? But more is expected of you than that.
5 – You can serve Islam by following in the footsteps of the scholars, daa’iyahs and reformers, having patience as your companion and putting up with tiredness and exhaustion. For you are doing a great act of worship which is the mission of the Prophets and Messengers and those who follow in their footsteps.
6 – You can serve Islam by shunning laziness, weakness and apathy, for this religion is the religion of resolve, ambition and courage, and its call is only harmed by laziness or reckless ignorance.
7 – You can serve Islam by connecting your heart to Allaah and reciting a lot of du’aa’ and prayers for forgiveness, and persisting in reading Qur’aan. There is nothing that is more effective in cleansing the heart and refreshing the soul, and making it active and energetic so that it will not get tired or bored, than remembering Allaah much and drawing nearer to Him by means of obeying Him and doing naafil (supererogatory) acts of worship.
8 – You can serve Islam by forming bonds with scholars who practise what they preach, those who are known to be sincere and who are well established in jihad and supporting this religion. Marching under their banner and following their lead is very good and beneficial.
9 – You can serve Islam by organizing your time on a daily, weekly and monthly basis. There are actions which should be done every day, others which should be done every week, and others which should be done every month or every year.
For example, you should make da’wah to those whom you see every day and to those whom you see once a week. You may have a family gathering once a month, and there may be annual conferences, or journeys for Hajj or ‘Umrah once a year, and so on.
10 – You can serve Islam by paying it some attention and giving it some of your time, thoughts and money, and making it your main concern. So when you stand up, it is for Islam; when you walk, it is for Islam; when you think, it is for Islam; when you give, it is for Islam; when you sit, it is for Islam.
11 – you can serve Islam by hastening to contribute every time you find an opportunity to do good. Do not hesitate or delay or put it off.
