As you start your prayer, make a definitive mental declaration to yourself that you are about to perform the Tahajjud. Decide that you are going to complete the Tahajjud in the specific way you have chosen, including how many rakats and which surahs you will recite. Also decide why you are saying the Tahajjud — for instance, to glorify Allah, thank Allah or ask for His forgiveness. You don't have to make this declaration out loud — Allah knows your thoughts, so your intentions will be clear to him as long as they are clear to you. The Tahajjud is typically performed by repeating multiple rakats (cycles) of Salah, the ritual that Muslims use for their required daily prayer. For the Tahajjud, the rakats are usually performed in pairs, so you'll also want to decide exactly how many rakats you intend to perform at this time. See below for more information. To begin your Tahajjud, start by performing two rakats (cycles) of Salah. Salah begins by standing and reciting verses from the Holy Quran. Then, the person praying continues by bowing low with his hands on his knees, then  prostrating on the ground with his forehead, nose, and palms on the floor and his elbows raised, sitting on his knees with his feet folded under him, and finally standing and reciting "Allahu Akbar." This description of Salah is a generalization — if you're not sure how to perform Salah properly, learn this fundamental Muslim skill before attempting the Tahajjud. Emulate the practices of the Prophet Muhammad (pbuh) who used to recite the following surahs after each rakat in Tahajjud: After reciting the Al-Fatihah the first rakat, recite the surah "Al-Kafirun". After reciting the Al-Fatihah for the second rakat, recite the surah "Al-Ikhlas". Generally, two rakats is seen as the minimum necessary for a proper Tahajjud. However, it's possible to repeat as many more as you wish. For instance, according to the Hadiths, the Prophet Muhammad frequently prayed up to thirteen rakats. Tahajjud rakats are performed in pairs and eight rakats is seen as a good number by many Muslims. In other words, most people will say two, four, six, or eight rakats, though more is not discouraged.  If you are able to, then reciting long surahs such as Al-Baqarah, An-Nisā’ or Al-‘Imran are highly commended, even if you can manage them only from time to time. Following in the example of the Prophet Muhammad (pbuh), if you notice dawn approaching while you say your Tahajjud, you may end by performing one rakat as Witr (an optional pre-dawn prayer said before the required Fajr). After you've completed the number of rakats you set out to pray, you may add your own dua as long as they're sincere, respectful, and done in complete devotion to Allah. These may be offered in extended prostration in your own words and language. You may want to offer additional thanks and praise to Allah, pray for strength and guidance, or make a special request for help. For instance, you may ask for blessings for a friend who is suffering through difficult times or help with your own worship or simply spend a few moments thanking Allah for a blessing that He granted you the previous day. Prayers should be offered with humbleness, fear, hope and patience. This is an ideal time to ask for forgiveness for your mistakes and sins as Allah is especially open to our repentance at night according to many ahadeeth.  Acknowledge each of your wrongdoings, however big or small - you may feel that some are insignificant, but Allah may still decide that a penalty is due. Sincerely promise not to repeat your sins and ask Allah for forgiveness. Use the fear of displeasing Allah to drive yourself to become a better Muslim. Never lose hope of Allah's mercy for the Qur'an tells us more than 70 times that Allah is the Most Forgiving. Any prayer you offer will be heard, and, if Allah wills, your prayer will be answered in kind. Because the Tahajjud interrupts your normal sleep, it's not unlikely that you may be somewhat tired when you attempt the prayer. If, however, you're so tired that you find yourself forgetting what you're saying as you recite your prayers or you doze off in the middle of your Tahajjud, don't attempt to complete the prayer. In this case, according to several ahadeeth, Allah notes your sincere willingness to complete the Tahajjud. You may go back to sleep without any need to be embarrassed or ashamed, but try to better prepare yourself next time, perhaps by going to bed earlier.
اجعل نيتك صادقة للصلاة. قم بأداء ركعتين في بداية الصلاة. يمكنك أداء عدد الركعات الذي تريد، فبشكل عام، ركعتا البداية هما أساس صلاة التهجد، ولكن يمكنك زيادة عدد الركعات كما تود. بعد الانتهاء من عدد الركعات الواجبة، يمكنك زيادة تلك الركعات طالما صادقة وخالصة النية لله. إن أصابك الإرهاق ولم تتمكن من استكمال الصلاة، عُد للنوم.
