Al-Allaamah Ubaid Ibn Abdillaah Al-Jaabiri (may Allaah preserve him) said:
There is none who hid (or hides) behind the Sunnah– the people beguiled by him, gathered around him to learn, adhered to him, became dependent on him and accepted everything he said–except that Allaah will reveal his affair, uncover and expose his concealed state of affairs to specific individuals and to the general public, regarding what was hidden and apparent of his deception, his mixing truth with falsehood, his plots and deceitful practices. Allaah facilitates men of virtue, intelligence, wisdom, strength and exceptional natural ability–possessors of knowledge, skill and sound understanding of the religion–through whom He (Allaah) unveils the affair of that trickster, dubious and deceitful person. www.sahab.net/home/?p=329
Thaabit Al-Bunaanee (rahimahullaah) used to pray at night and fast during the day. He used to say: ‘’There is nothing I find more pleasing to my heart than Qiyaamul Layl (i.e. Tahajjud)’’ [Sifatus Safwah 3/262]
Maymoon Ibn Mehraan (rahimahullaah) said:
”The nobility of a Muslim is in performing the prayer in the darkness of night and not being desperate for what is in the hands of the people (i.e. their possessions) [Shu’ab Al-Imaan 3/171]
We ask Allaah to grant us the tawfeeq to follow the example of our Salaf. However, if Allaah grants you the Tawfeeq to wake up for the night prayer, do not stand up all night and then oversleep and miss fajr; rather ask Allaah for tawfeeq to wake up in the last third of the night until the beginning of Fajr.
