Da‘wah (also transliterated daawa(h); Arabic: دعوة “invitation”) means the proselytizing or preaching of Islam. Da‘wah literally means “issuing a summons” or “making an invitation”, being a gerund of a verb meaning variously “to summon” or “to invite”. A Muslim who practices da‘wah, either as a religious worker or in a volunteer community effort, is called a dā‘ī (داعي, plural du‘āh/du‘āt ).
A dā‘ī is thus a person who invites people to understand Islam through dialogue, not unlike the Islamic equivalent of a missionary inviting people to the faith, prayer and manner of Islamic life. 
In Surah Nuh, we see the character of Prophet Nuh alayhi salaam as a da’ee, who faced difficulties in spreading Islam.The Surah begins with Allah subhanahu wa ta’ala telling us how Prophet Nuh [Noah]‘alayhi salaam began calling his people to Allah subhanahu wa ta’ala. His dawah methodology is gem for all. There are some lessons in the ayah 5- 9, that what should be the character of a da’ee and what attributes are required for this task:
Lessons for da’ee:
Relentlessly pursuing goals
Patience during this time
Consistency in efforts
Using all potential
Never giving up
Having firm connection with Allah
Using different techniques according to audience at different times

The Tahajjud is a special Islamic prayer which is recommended (but not required) for all Muslims. The Tahajjud is prayed after Isha (the required nightly prayer) and before Fajr (the required morning prayer). If possible, it is most desirable to perform the Tahajjud between midnight and Fajr, preferably in the last third of the night. Though the Tahajjud isn’t required, many devout Muslims try to make it part of their daily routine as a sign of their devotion and as an opportunity to earn redemption and forgiveness from Allah. 
There are some easy tips that can help one to wakeup for tahajjud:
Go to bed early and rest
After the Isha prayer, the Prophet ﷺ would not like to engage in unnecessary talk and would go to his house to go to sleep.Societies that maintain going down with the sun inevitably rise with the sun, making the most of their ‘ibaadah or secure their livelihood.
By taking a nap after Dhuhr is one of the sunnah of our Prophet ﷺ. It is a great source of revitalizing your body and mind. This is one of the most effective tip to wake up one self early for ibadah.
Untie your three knots:
“During your sleep, Satan knots three knots at the back of the head of each of you, and he breathes the following words at each knot, ‘The night is, long, so keep on sleeping,’ . If that person wakes up and celebrates the praises of Allah, then one knot is undone, and when he performs ablution the second knot is undone, and when he prays, all the knots are undone, and he gets up in the morning lively and in a good mood, otherwise he gets up dull and gloomy. ” (Bukhari)
Celebrate the praises of Allah by saying:
Alhamdulillahi allathee ahyaanaa ba’da maa amaatanaa wa ilayhin nushoor “ٓAll praises be to Allah, who gave us life after killing us (sleep is a state of death) and to Him we will be raised and return ” (Sahih Bukhari, Sahih Muslim)
1. Perform ablution
2. Perform the prescribed dhikr adkhar

“The angels keep on asking Allah’s forgiveness for anyone of you, as long as he is at his Musalla (praying place) and he does not pass wind (Hadath). They say, ‘O Allah! Forgive him, O Allah! be Merciful to him.” (Bukhari)
