Last week I was reminded by the ustaz who came to teach Qur'an and Arabic to my son about the importance of learning tasawwuf in order to enhance/complete our iman(kesempurnaan iman).His statement reminds me of another ustaz who taught us that Ilmu Fardu 'Ain( a must for every muslim/muslimah) consists of Tauhid, Fiqah and Tasawwuf.For most of us who did not go to religous school( I am one of them), our knowledge is limited to basic Tauhid and Fiqah and very little in Tasawwuf. I realised this lacking of knowledge when I crossed my 40's.
Most of us have heard of one long Hadith narrated by Saiyidina Umar al-Khattab r.a about Jibrail a.s came to Prophet Muhammad s.a.w and asked him about the meanings of Islam,Iman and Ihsan.To understand Ihsan ,we need the knowledge of tasawwuf-it articulates and discuss the issues of Ihsan.
If you wish to learn more about tasawwuf, I recommend the following books(all in Malay language):
1.Tasawwuf Moden by Dr Hamka(passed away)
2.Pengantar Tasawwuf Islam by Dr Musa Fatullah Harun( still teaching in KL)
May I remind myself and my fellow muslims/muslimahs to continously upgrading the breadth and depth of our knowledge on Islam.
