On La Ilaha Illah recite La Ilaha Illah.

At the time of Aqamah, only at the time of Ashadu Anna Muhamadur Rasoolullah we should recite Sallallahu alaihi wa sallam and at the time of Qad Qamatis Salaat, we should recite: Aqamahallahu and Adamaha.

Taken from Mawaaiz-e-Hasana of Hadhrat Muhaddith-e-Deccan (May Allah sanctify his soul)

Blessing of Halal earnings and staying away from Haraam earnings:

Taken from Mawaaiz-e-Hasana of Hadhrat Muhaddith-E-Deccan (May Allah SWT shower His Mercy on him)

Hadhrat Shaykh Abu Ali Daqqaq (May Allah Ta’ala shower His Mercy on him) says: The person who leaves Haraam wealth will be saved from Hell; the person who stays away from doubtful wealth will not enter Hell and the person who saves himself from asking for more will earn proximity ( Qurb ) of Allah (Subhanahu Wa Ta’ala) (the actual words used are wasil il Allah).

Hadhrat Imam Ghazali (May Allah Ta’ala shower His Mercy on him) says:  Sin is a great veil.  The heart of the person who insists on sins becomes dark and especially Haram earnings will destroy like anything.  The Noor created in the heart by Halal earnings is not created by anything else.  Thus, a Salik should save himself from Haram earnings and should not eat anything except what is Halaal.
