The source warns against ishbāʿ where there is no following matching madd letter: do not turn bare fatḥah, ḍammah or kasrah into an unintended long vowel. Overlengthening creates the impression of an extra letter.
Practice: avoid changing «قَ» to «قَا», «قُ» to «قُو», or «قِ» to «قِي». These are illustrative comparisons, not interchangeable readings.
