While the work is voluntary Mu'akkad law, which is highly recommended for voluntary work for people who need them. As which has been described in the word of Allah which means:
"O those who believe, seek help (to ALLAH) with patience and sholat, for Allah is with those who patiently
(Surat al-Baqara: 153)
And also the word - in his letter Yusuf verse 87 which means:
"And do you despair of the Mercy of Allah, for verily none despair of the Mercy of Allah, except those who disbelieve"
In a hadith which in riwayatkan by Imam Ibn Majah Turmudzi and 'Abdullah bin Abi Auf ra also explained, that Rasull SAW had said what means:
"He who has the intent (the need) to ALLAH or to one of the sons of Adam, let him wudhunya perfect ablution and then shalat two rakaat, then let him say praise to ALLAH and say shalawat to the Prophet SAW, and then let him pray.
