(Muhammad) 47 : 17
وَالَّذِينَ اهْتَدَوْا زَادَهُمْ هُدًى وَآتَاهُمْ تَقْوَاهُمْ
And those who are utilising the Guidance, for them He will increase Guidance and will grant them their heedfulness.
The Guidance and Heedfulness mentioned in this verse is Adhikr. Therefore, to increase Guidance and Heedfulness, Adhikr should be followed in the best manner. See explanation 39:23, 33; and 42:52.
